The ATP Yield from Complete Oxidation of Glucose
We have discussed many aspects of the complete oxidation of glucose to carbon dioxide and water. At this point, it is useful to do some bookkeeping to see how many molecules of ATP are produced for each molecule of glucose oxidized. Recall that some ATP is produced in glycolysis, but that far more ATP is produced by aerobic metabolism. Table 20.3 summarizes ATP production and also follows the reoxidation of NADH and FADH2.
In the complete oxidation of glucose, a total of 30 or 32 molecules of ATP are produced for each molecule of glucose, depending on the shuttle mechanism.
