Botany - Respiration in Plants Question with Solution | TestHub

The net gain from complete oxidation of a glucose molecule in aerobic respiration is 36 ATP molecules. 10 molecules of ${\mathrm{NADH}}_2$ ( 2 from Glycolysis +8 from Krebs' cycle) yield $=10\times 3=30\mathrm{ATP},2$ molecules of ${\mathrm{FADH}}_2$ yield $=2\times 2=4$ ATP and glycolysis also yields 2 ATP. Therefore, total release of ATP per hexose will be $=30+4+2=36$ ATP.
