    Study Notes

    Cellular Respiration

    • ATP is produced during oxidative phosphorylation
    • Water is produced during the electron transport chain
    • Carbon dioxide is released during the Krebs cycle
    • ATP synthase is the enzyme responsible for catalyzing the synthesis of ATP

    Photosynthesis

    • The Calvin cycle takes place in the stroma of the chloroplast
    • The primary product of the Calvin cycle is glucose
    • The light-dependent reactions occur in the thylakoid membrane
    • Photophosphorylation is the process of converting light energy into chemical energy
    • NADP+ captures and transfers electrons during photosynthesis

    Electron Transport Chain

    • The electron transport chain generates a proton gradient
    • Oxygen is the final electron acceptor in the electron transport chain
    • The electron transport chain is involved in the production of ATP

    Glycolysis

    • Glycolysis is the breakdown of glucose in the presence of oxygen
    • Pyruvate is produced during glycolysis
    • The net gain of ATP molecules during glycolysis is 2 ATP

    Other Processes

    • Fermentation is the breakdown of glucose in the absence of oxygen
    • Anaerobic respiration in humans produces lactic acid as a byproduct
    • The ATP synthase complex is involved in the production of ATP during cellular respiration
    • ATP is primarily used for energy storage in cellular processes
    • Aerobic respiration takes place in the mitochondrion
    • The primary function of the Krebs cycle is to produce ATP and NADH
