    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.
