Detailed explanation-1: -One molecule of NADH is equivalent to two ATP in the cytoplasm. One NADH molecule is equivalent to three ATP molecules inside the mitochondria. Hence, in total 30 ATP molecules are generated by 10 NADH molecules during aerobic respiration.
Detailed explanation-2: -4 ATP and 2 NADH molecules are formed and as well as two molecules of pyruvate. The end product of Glycolysis, pyruvate, is transported into the mitochondrion and converted to a compound called acetyl coenzyme A or acetyl CoA.
Detailed explanation-3: -In aerobic respiration, the full oxidation of one glucose molecule can theoretically yield 38 ATP molecules.
Detailed explanation-4: -Cellular respiration produces a maximum of 10 NADH and 2 FADH2 per glucose molecule. Since a single NADH produces 2.5 ATP and a single FADH2 produces 1.5 ATP, it follows that 25 ATP + 3 ATP are produced by oxidative phosphorylation.
