Detailed explanation-1: -The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS). The inner mitochondrial membrane holds the ATPase enzyme and the complexes for ETS.

Detailed explanation-2: -The majority of ATP synthesis occurs in cellular respiration within the mitochondrial matrix: generating approximately thirty-two ATP molecules per molecule of glucose that is oxidized.

Detailed explanation-3: -Answer and Explanation: Most of the ATP energy obtained from cellular respiration is produced in the third and final stage, the electron transport chain. In the electron transport chain, electrons are passed from one acceptor to the next, in a series of redox reactions.

Detailed explanation-4: -The Electron transport chain is the third stage of cellular respiration and is illustrated in Figure 4.10. 8. During this stage, high-energy electrons are released from NADH and FADH2, and they move along electron-transport chains on the inner membrane of the mitochondrion.

Detailed explanation-5: -Mitochondria Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
