There are net 38 ATP molecules are produced by the complete metabolism( all pathways) of one glucose molecules
Theoretically, 38 ATP molecules are produced by complete oxidation of one patch of glucose in aerobic respiration. The net ATP gain from one glucose patch in aerobic respiration is 38 ATP.
It includes ATP produced in glycolysis, link response, TCA cycle and by oxidative phosphorylation in the electron transport system from oxidising NADH and FADH2, which produces 3 ATP and 2 ATP, independently. Glycolysis - 2 ATP and 2 NADH Link Response( pyruvate to acetyl CoA) - 2 NADH TCA cycle - 2 ATP, 6 NADH and 2 FADH2
