Question

Transcribed Image Text:When one molecule of glucose undergoes glycolysis, two molecules of
pyruvate are produced; the pyruvates then undergoes oxidative
decarboxylation to yield two acetyl CoA. How many net molecules of ATP
are produced by the oxidative decarboxylation of two molecules of
pyruvate to yield two acetyl COA?
