AP Biology Unit 2: Cell Structure and Function ー Study Guide Plan

This comprehensive study plan focuses on core concepts like cell structure, transport, and organelles, utilizing FRQ practice and MCQs for AP Biology success.

Overview of Unit 2

Unit 2 of AP Biology delves into the foundational principles of cell structure and function, representing approximately 10-13% of the AP Exam. This unit establishes a crucial understanding of life’s basic unit – the cell – and its intricate components. Students will explore the differences between prokaryotic and eukaryotic cells, analyzing how cell size impacts efficiency through surface area to volume ratios.

A significant focus lies on cell membranes, examining the phospholipid bilayer and the roles of embedded proteins in transport mechanisms. Furthermore, the unit details the functions of various organelles, from the nucleus controlling cellular activities to mitochondria generating energy. Mastering these concepts is vital, as they underpin many subsequent topics in the course, and are frequently assessed through multiple-choice questions and free-response questions.

Cell Structure and Function: Core Concepts

Central to Unit 2 are several core concepts that define cellular life. Understanding the relationship between structure and function is paramount; each cellular component’s shape directly relates to its role. The concept of homeostasis – maintaining a stable internal environment – is crucial, heavily influenced by membrane permeability and transport mechanisms;

Energy processing, particularly through cellular respiration, is another key theme, linking organelle function to overall organismal survival. Furthermore, the importance of compartmentalization within eukaryotic cells, facilitated by organelles, allows for specialized functions and increased efficiency. Finally, recognizing the evolutionary origins of cell structures, differentiating prokaryotic from eukaryotic forms, provides a foundational understanding of life’s diversity.

Prokaryotic vs. Eukaryotic Cells

A fundamental distinction in biology lies between prokaryotic and eukaryotic cells. Prokaryotic cells, like bacteria and archaea, lack a nucleus and other membrane-bound organelles; their DNA resides in a nucleoid region. They are generally smaller and simpler in structure. Eukaryotic cells, found in protists, plants, animals, and fungi, possess a true nucleus housing their DNA, alongside various organelles like mitochondria and the endoplasmic reticulum.

This compartmentalization allows for specialized functions and greater complexity. Eukaryotic cells are typically larger than prokaryotic cells. Understanding these differences is crucial, as they reflect distinct evolutionary pathways and impact cellular processes. Consider the implications for surface area to volume ratios and metabolic efficiency in each cell type.

Cell Size and Surface Area to Volume Ratio

Cell size is critically constrained by the surface area to volume ratio (SA:V). As a cell increases in size, its volume grows faster than its surface area. The surface area is vital for nutrient uptake, waste removal, and gas exchange – all essential for cell survival. A smaller SA:V ratio means less membrane available relative to the cell’s volume, hindering efficient transport.

This limitation explains why cells are generally microscopic. Larger cells require strategies to increase their SA:V, such as cell compartmentalization (organelles) or elongated shapes. Understanding this principle is key to grasping how cells function and adapt to their environments. Fiveable highlights this as a core concept for AP Biology.

Cell Membrane Structure

The cell membrane, a crucial boundary, is primarily composed of a phospholipid bilayer. This structure provides a selectively permeable barrier, controlling what enters and exits the cell. Phospholipids arrange themselves with hydrophilic heads facing outwards (water-loving) and hydrophobic tails inwards (water-fearing), creating a stable structure.

However, the membrane isn’t just lipids! Membrane proteins are embedded within the bilayer, performing diverse functions like transport, enzymatic activity, and cell signaling. These proteins can be integral (spanning the membrane) or peripheral (on the surface). Understanding the fluid mosaic model – the dynamic arrangement of lipids and proteins – is fundamental to grasping membrane function.

Phospholipid Bilayer

The phospholipid bilayer forms the fundamental structure of the cell membrane, acting as a barrier between the cell’s internal environment and its surroundings. Each phospholipid molecule possesses a hydrophilic (water-attracting) head containing a phosphate group and two hydrophobic (water-repelling) fatty acid tails.

These molecules spontaneously arrange themselves into a bilayer in an aqueous environment, with the hydrophobic tails facing inward, shielded from water, and the hydrophilic heads facing outward, interacting with the watery environments both inside and outside the cell. This arrangement creates a selectively permeable barrier, crucial for cellular function. The fluidity of the bilayer is influenced by temperature and the saturation of fatty acid tails.

Membrane Proteins and Their Functions

Membrane proteins are integral or peripheral components embedded within or associated with the phospholipid bilayer, performing diverse and critical functions. Integral proteins span the entire membrane, often acting as channels or carriers to facilitate the transport of molecules across the membrane. Peripheral proteins are loosely bound to the surface, providing structural support or participating in signaling pathways.

These proteins mediate cell communication, enzymatic activity, and cell-cell recognition. Transport proteins enable selective permeability, while receptor proteins bind signaling molecules initiating cellular responses. Understanding protein structure and function is key to grasping membrane dynamics. Their roles are vital for maintaining cellular homeostasis and responding to environmental cues.

Membrane Transport

Membrane transport governs the movement of substances across the cell membrane, crucial for maintaining cellular homeostasis. This process is broadly categorized into passive and active transport mechanisms. Passive transport, requiring no energy expenditure, includes diffusion, osmosis, and facilitated diffusion – all driven by concentration gradients.

Active transport, conversely, demands energy (typically ATP) to move substances against their concentration gradients. This includes protein pumps, endocytosis (bringing substances into the cell), and exocytosis (releasing substances from the cell). Understanding these mechanisms is fundamental to comprehending nutrient uptake, waste removal, and cellular signaling. The selective permeability of the membrane is key.

Passive Transport (Diffusion, Osmosis, Facilitated Diffusion)

Passive transport relies on the natural tendency of molecules to move from areas of high to low concentration, requiring no cellular energy expenditure. Diffusion is the movement of any substance down its concentration gradient. Osmosis, a specific type of diffusion, focuses on water movement across a selectively permeable membrane.

Facilitated diffusion utilizes membrane proteins to assist in the transport of polar or charged molecules that cannot easily cross the lipid bilayer. These proteins act as channels or carriers, speeding up diffusion. Understanding water potential and tonicity (hypotonic, hypertonic, isotonic) is vital for grasping osmosis. These processes are essential for nutrient uptake and waste removal.

Active Transport (Pumps, Endocytosis, Exocytosis)

Active transport mechanisms require energy, typically in the form of ATP, to move substances against their concentration gradients. Pumps, like the sodium-potassium pump, are integral membrane proteins that facilitate this movement. This process maintains cellular gradients crucial for nerve impulse transmission and other functions.

Endocytosis involves the cell engulfing materials by forming vesicles from the plasma membrane – phagocytosis (“cell eating”) and pinocytosis (“cell drinking”) are examples. Conversely, exocytosis releases materials from the cell. These bulk transport methods are vital for large molecule transport and cellular communication. Mastering these concepts is key to understanding cellular energy use.

Cellular Organelles: Structure and Function

Cellular organelles are specialized subunits within a cell, each performing distinct functions. The nucleus controls cellular activities, housing DNA, while the nucleolus is responsible for ribosome synthesis. Ribosomes themselves are the sites of protein synthesis. The endoplasmic reticulum (ER), both rough and smooth, plays roles in protein and lipid production, respectively.

The Golgi apparatus processes and packages proteins. Lysosomes contain enzymes for intracellular digestion, and vacuoles store materials. Mitochondria are the powerhouses of the cell, generating ATP, while chloroplasts (in plant cells) conduct photosynthesis. Understanding each organelle’s structure and function is fundamental to grasping cellular processes.

Nucleus and Nucleolus

The nucleus, the control center of the eukaryotic cell, is enclosed by a double membrane called the nuclear envelope, regulating transport. Within, DNA organizes into chromosomes, carrying genetic information. The nucleolus, a prominent structure inside the nucleus, is crucial for ribosome biogenesis. It synthesizes ribosomal RNA (rRNA) and assembles ribosomal subunits.

These subunits are then exported to the cytoplasm for protein synthesis. The nucleus ensures genetic integrity and controls cellular activities by regulating gene expression. Understanding the nucleus and nucleolus is vital for comprehending cell division, protein production, and overall cellular function. Their coordinated action is essential for life.

Ribosomes

Ribosomes are complex molecular machines responsible for protein synthesis, translating genetic code from mRNA into polypeptide chains. They are found in all living cells, existing as free-floating entities in the cytoplasm or bound to the endoplasmic reticulum (ER), forming rough ER. Ribosomes consist of two subunits – a large and a small subunit – composed of rRNA and proteins.

Their structure facilitates tRNA binding and peptide bond formation. Ribosomes play a critical role in gene expression and cellular function. Differences exist between prokaryotic and eukaryotic ribosomes, impacting antibiotic targeting. Understanding ribosome structure and function is fundamental to grasping the central dogma of molecular biology and cellular processes.

Endoplasmic Reticulum (Rough & Smooth)

The Endoplasmic Reticulum (ER) is a network of membranes involved in protein and lipid synthesis. It exists in two forms: Rough ER and Smooth ER. Rough ER is studded with ribosomes, giving it a “rough” appearance, and is primarily involved in protein folding, modification, and transport. Proteins destined for secretion or membrane insertion are processed here.

Smooth ER lacks ribosomes and is crucial for lipid synthesis, carbohydrate metabolism, and detoxification of drugs and poisons. It also stores calcium ions. The ER’s extensive surface area increases its capacity for these vital functions. Understanding the distinct roles of each ER type is essential for comprehending cellular organization and function.

Golgi Apparatus

The Golgi Apparatus, often described as the “shipping and receiving center” of the cell, further processes and packages proteins and lipids synthesized in the ER. It consists of flattened, membrane-bound sacs called cisternae, arranged in stacks. Molecules travel from the cis face (receiving side) to the trans face (shipping side), undergoing modifications along the way.

These modifications include glycosylation, phosphorylation, and sulfation; The Golgi then sorts and packages these molecules into vesicles for transport to other organelles or secretion outside the cell. Proper Golgi function is critical for cellular communication and maintaining cellular organization. Understanding its structure and function is key to mastering cell biology.

Lysosomes

Lysosomes are membrane-bound organelles functioning as the cell’s digestive system. They contain hydrolytic enzymes capable of breaking down a wide range of macromolecules – proteins, lipids, carbohydrates, and nucleic acids – through hydrolysis. These enzymes work best in an acidic environment, maintained within the lysosome.

Lysosomes play a crucial role in intracellular digestion, breaking down worn-out organelles (autophagy) and engulfing foreign materials like bacteria (phagocytosis). They are essential for cellular recycling and defense. Defects in lysosomal function can lead to various storage diseases, highlighting their importance in maintaining cellular health and overall organismal function.

Vacuoles

Vacuoles are large, membrane-bound sacs with diverse functions depending on the cell type. In plant cells, the central vacuole is prominent, storing water, ions, pigments, and waste products. It maintains turgor pressure, providing structural support. Animal cells possess smaller vacuoles used for storage and transport.

Vacuoles also participate in detoxification, breaking down harmful substances. Contractile vacuoles, found in some protists, pump excess water out of the cell, maintaining osmotic balance. Their versatility makes them essential for cellular homeostasis and adaptation to varying environmental conditions. Understanding vacuole function is key to grasping plant and animal cell differences.

Mitochondria

Mitochondria are often called the “powerhouses” of the cell, and for good reason! These double-membrane bound organelles are the primary sites of cellular respiration, generating ATP – the cell’s main energy currency. The inner membrane is highly folded into cristae, increasing surface area for ATP production.

Mitochondria possess their own DNA and ribosomes, supporting the endosymbiotic theory, suggesting they originated as independent prokaryotic organisms. They are crucial for nearly all eukaryotic cell functions requiring energy. Understanding their structure and role in ATP synthesis is fundamental to comprehending energy flow within biological systems and overall cell function.

Chloroplasts (Plant Cells)

Chloroplasts are the sites of photosynthesis in plant cells and some algae. Like mitochondria, they have a double membrane structure and their own DNA and ribosomes, also supporting the endosymbiotic theory. Inside, you’ll find thylakoids, flattened sac-like structures arranged in stacks called grana, where the light-dependent reactions occur.

The fluid-filled space around the thylakoids is the stroma, where the Calvin cycle takes place. Chloroplasts capture light energy to convert carbon dioxide and water into glucose, providing energy for the plant. Understanding their structure and function is vital for grasping energy production in autotrophic organisms and the interconnectedness of life.

Cell Communication

Cell communication is crucial for coordinating activities within multicellular organisms. Cells communicate through various mechanisms, including cell junctions – direct connections allowing small molecules to pass between cells. More commonly, cells utilize signal transduction pathways, where signaling molecules bind to receptors triggering a cascade of events inside the cell.

These pathways often involve phosphorylation cascades and second messengers, ultimately leading to a cellular response. Understanding different signaling types – paracrine, autocrine, endocrine, and direct contact – is key. Disruptions in cell communication can lead to diseases like cancer, highlighting its importance in maintaining homeostasis and proper function.

Cell Junctions

Cell junctions are specialized structures that connect cells, enabling direct communication and maintaining tissue integrity. There are several types, including tight junctions, creating a seal preventing leakage; desmosomes, providing strong adhesion; gap junctions, allowing small molecules to pass directly between cells; and plasmodesmata, found in plant cells, facilitating transport.

These junctions aren’t merely structural; they play vital roles in coordinated function. For example, gap junctions are crucial for rapid signaling in the heart. Understanding the structure and function of each type is essential for comprehending how tissues and organs operate as cohesive units. Dysfunction in cell junctions can contribute to various diseases.

Signal Transduction Pathways

Signal transduction pathways are crucial for cellular communication, converting external signals into intracellular responses. These pathways typically involve three stages: reception, where a signaling molecule binds to a receptor; transduction, a multi-step process often involving protein kinases and second messengers; and response, the final cellular change.

Common pathways include G protein-coupled receptors, receptor tyrosine kinases, and ion channel receptors. Understanding these pathways is vital as they regulate numerous cellular processes, including growth, metabolism, and gene expression. Errors in signal transduction can lead to diseases like cancer. Studying these complex systems requires recognizing the sequential nature of events and the amplification of signals.

Cellular Respiration and Energy Production

Cellular respiration is the process by which cells break down glucose to generate ATP, the primary energy currency of life. This complex process involves several stages: glycolysis, occurring in the cytoplasm; the Krebs cycle (citric acid cycle) and electron transport chain, taking place within the mitochondria.

Understanding the inputs and outputs of each stage, including NADH and FADH2, is crucial. Aerobic respiration requires oxygen and yields significantly more ATP than anaerobic respiration (fermentation). Factors influencing respiration rates, like temperature and substrate availability, should also be considered. Mastering this topic is essential for understanding energy flow in biological systems.

Cell Cycle and Mitosis

The cell cycle is a repeating series of growth, DNA replication, and division, consisting of Interphase (G1, S, G2 phases) and the Mitotic (M) phase. Mitosis, the division of the nucleus, comprises prophase, metaphase, anaphase, and telophase. Understanding the events occurring in each phase – chromosome condensation, alignment, separation, and nuclear envelope reformation – is vital.

Cytokinesis, the division of the cytoplasm, typically follows mitosis. Checkpoints within the cell cycle ensure accurate DNA replication and segregation. Errors in these processes can lead to uncontrolled cell growth and potentially cancer. Knowing the purpose and regulation of the cell cycle is fundamental to understanding growth and development.

Meiosis and Genetic Variation

Meiosis, unlike mitosis, is a reduction division process resulting in four genetically unique haploid daughter cells. It consists of Meiosis I (Prophase I, Metaphase I, Anaphase I, Telophase I) and Meiosis II, mirroring mitosis. Prophase I is crucial, featuring crossing over – the exchange of genetic material between homologous chromosomes – contributing significantly to genetic variation.

Independent assortment of chromosomes during Metaphase I further increases diversity. Understanding the differences between mitosis and meiosis, and the mechanisms generating genetic variation (crossing over, independent assortment, random fertilization) is key. These processes are fundamental to sexual reproduction and evolution.
