True, reactions that generate the largest amounts of ATP during cellular respiration take place in the mitochondria.
Electron Transport System can generates 32 or 34 ATP molecules and this is considered as the main source of energy. Hence, the electron transport system produces the most ATP in cellular respiration. On the other hand the other metabolic cycle that provides the highest net ATP per molecule of glucose is known as oxidative phosphorylation. In the mitochondria, aerobic respiration produces the greatest ATP per glucose module.
Oxidative phosphorylation also responsible for producing 1.5 ATP molecules from FADH2, or from the NADH molecules that is produced through glycolysis in the cytosol.
