WebApr 20, 2024 · Determine the amount of ATP produced by the oxidation of glucose in the presence and absence of oxygen. Determining the exact yield of ATP for aerobic respiration is difficult for a number of reasons. First of all, the number of ATP generated per reduced NADH or FADH 2 is not always a whole number. WebDec 17, 2024 · The electrons temporarily stored in molecules of NADH and FADH 2 are used to generate ATP in a subsequent pathway. One molecule of either GTP or ATP is produced by substrate-level phosphorylation on each turn of the cycle. There is no comparison of the cyclic pathway with a linear one. Review Questions
