    Study Notes

    • Aerobic respiration requires oxygen and is the preferred method when oxygen is available to cells, involving a series of steps using different enzymes to produce carbon dioxide, water, around 30-32 ATP, and heat.
    • Anaerobic respiration occurs when oxygen is not readily available, resulting in the production of lactic acid, only two ATP molecules, and a little bit of heat, with pyruvate as the final electron acceptor.
    • Both aerobic and anaerobic respiration start with glycolysis, which is the breakdown of glucose in the cytoplasm using various enzymes and involving an energy investment stage with an initial use of 2 ATP molecules.
    • Glycolysis yields NADH, a few ATP molecules, and two pyruvate molecules from glucose, with the fate of pyruvate depending on the presence of oxygen.
    • If oxygen is not present, pyruvate is converted into lactic acid in the anaerobic pathway, resulting in two ATP molecules.
    • If oxygen is present, pyruvate is transported to the mitochondria for further reactions including the conversion to acetyl CoA, the Krebs Cycle, electron transport chain, and oxidative phosphorylation, ultimately producing water, carbon dioxide, and more ATP.
