(b) number of moles of ATP produced under aerobic glycolysis whereby pyruvate enters the mitochondrion for oxidative decarboxylation to generate acetyl-CoA that enters the citric acid cycle. Write the reac- tions for each step using words. They need not be balanced with respect to charge, protons released or consumed, and stoichiometry. Consider 2.5 ATP/NADH oxidized and 1.5 ATP/FADH2 oxidized. Enzymes need not be named.
