    Study Notes

    Photosynthesis

    • Reactants are carbon dioxide (CO₂) and water (H₂O).
    • Products consist of carbohydrates (C₆H₁₂O₆) and oxygen (O₂), essential for life.

    Cellular Respiration

    • Reactants include carbohydrates (C₆H₁₂O₆) and oxygen (O₂).
    • Products are carbon dioxide (CO₂) and water (H₂O), releasing energy for cellular functions.

    Calvin Cycle

    • Reactant involves carbon dioxide (CO₂), which is fixed during the process.
    • Products are carbohydrates, serving as energy sources for organisms.

    Krebs Cycle

    • Starts with pyruvate, derived from glycolysis.
    • Produces carbon dioxide (CO₂) as a waste product and energy-carrying molecules like NADH and FADH₂, contributing to ATP generation.

    Glycolysis

    • Reactants are 2 ATP and glucose (C₆H₁₂O₆).
    • Produces a net gain of 2 ATP, 2 pyruvate molecules, and 2 NADH, occurring in the cytoplasm.

    Lactic Acid Fermentation

    • Reactants include 2 pyruvate and glucose (C₆H₁₂O₆).
    • Produces NAD⁺ and 2 lactic acid molecules, allowing glycolysis to continue in anaerobic conditions.

    Alcoholic Fermentation

    • Reactants involve 2 pyruvate and NADH.
    • Products consist of 2 alcohol (ethanol), 2 carbon dioxide (CO₂), and 2 NAD⁺, occurring in yeast under anaerobic conditions.
