Unformatted text preview: receptor-mediated and end product processes. Carbohydrate Metabolism • Glycolysis is the breakdown of glucose to two pyruvic acid molecules. Two ATP molecules are also produced. • Anaerobic respiration is the breakdown of glucose in the absence of oxygen to two lactic acid molecules and two ATP molecules. • Lactic acid can be converted to glucose using aerobically produced ATP; the necessary oxygen is the oxygen debt. • Aerobic respiration is the breakdown of glucose in the presence of oxygen to produce carbon dioxide, water, and 38 molecules of ATP. o The first phase of aerobic metabolism is glycolysis. o The second phase of aerobic metabolism is the conversion of pyruvic acid to acetyl-CoA. o The third phase of aerobic metabolism is the citric acid cycle. o The fourth phase is the electron-transport chain, which uses carrier molecules such as NADH to synthesis ATP....
