For the theoretical maximum yield of ATP per glucose molecule oxidized by aerobic respiration, we will assume that for each pair of electrons transferred to the electron transport chain by NADH, 3 ATP will be generated; for each electron pair transferred by FADH2, 2 ATP will be generated.

The complete aerobic respiration of glucose yields far more energy stored in ATP than glycolysis alone for all of the following reasons EXCEPT: Krebs cycle generates reduced electron carrier molecules (NADH and FADH2) Krebs cycle generates some additional ATP through substrate-level phosphorylation Glycolysis only partially oxidizes the glucose molecule to pyruvic acid None of the other four answers (all are reasons that aerobic respiration yields more energy than glycolysis alone) Electron transport chain (terminal respiratory pathway) produces many ATPs through oxidative phosphorylation using electron carrier molecules (NADH and FADH2)
