Botany - Respiration in Plants Question with Solution | TestHub

Carbon dioxide evolved in HMP is higher than glycolysis. In this cycle for every molecule of CO₂released 2 NADPH₂are synthesized. Therefore, the complete oxidation of one glucose molecule would produce 6 CO₂molecules or$\left(6\times 2\right)=12$NADPH₂molecules.

Since each NADPH₂on its passage through the electron transport chain yields 3ATP, therefore, 12 NADPH₂would yield$(12\times 3)=36$ATP molecules.

Net gain of ATP is 36 -1 = 35 ATP
