Study Notes
Cell Structure and Function
- Plant vs. Animal Cells: Plant cells have cell walls and chloroplasts; animal cells lack these structures.
- Ribosomes: Ribosomes are not energy producers; they synthesize proteins.
- Lysosomes: Function in digestion and waste processing within cells.
Cellular Environment
- Red Blood Cells in Distilled Water: Human red blood cells will lyse (burst) when exposed to distilled water due to osmotic pressure.
Genetics and Meiosis
- Independent Assortment: Genes on nonhomologous chromosomes assort independently.
- Meiosis Outcome: Meiosis creates gametes with half the chromosome number; e.g., from a diploid number of 30, produces four gametes with 15 chromosomes each.
Enzymes and Metabolism
- Enzyme Characteristics: Enzymes are not consumed in reactions, often require cofactors, and are comprised of amino acids.
- Glycolysis Location: Glycolysis occurs in the cytoplasm of the cell.
Photosynthesis
- Calvin Cycle: Takes place in the stroma of chloroplasts and is essential for converting carbon dioxide into glucose.
- Fruit Ripening Hormone: Ethylene is the plant hormone responsible for fruit ripening.
Cellular Transport and Interaction
- Water Molecule Interaction: Cohesion helps with water movement through xylem vessels in plants.
- Dehydration Reaction Product: Water (H2O) is released during dehydration synthesis reactions.
Tissue and Organ Systems
- Muscle Types: Cardiac muscle is involuntary; striated skeletal muscle is voluntary.
- Epithelial Cells: Cover body surfaces and line cavities, playing vital roles in protection and secretion.
Bacteria vs. Viruses
- Structural Differences: Bacteria have a cellular structure with a membrane, while viruses are acellular and lack organelles.
Cellular Respiration
- Aerobic Respiration Equation: The overall reaction is C6H12O6 + O2 → CO2 + H2O + 36 ATP.
- Hydrogen Acceptor: Oxygen acts as a hydrogen acceptor during aerobic respiration.
Evolution and Genetics
- Biological Evolution Definition: Refers to changes in inherited traits in populations over generations.
- Transformation in Bacteria: Griffith's experiment demonstrated the transformation process, revealing that bacteria can exchange genetic material.
Miscellaneous Facts
- Cilia vs. Flagella: Cilia are shorter and more numerous than flagella.
- Apoptosis Functionality: Involves lysosomes and serves as programmed cell death for maintaining health.
- Peptide Bonds: Form between amino acids during protein synthesis.
Immune System
- Types of White Blood Cells: Phagocytes and lymphocytes are essential for immune responses, aiding in the identification and destruction of pathogens.
