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: -Electron Transport System generates 32 or 34 ATP molecules and is the cell’s main source of energy. Thus, the electron transport system produces the most ATP in cellular respiration.

Detailed explanation-3: -The protein ATP-synthase uses the energy liberated to create a proton gradient, which is then utilised in chemiosmosis to produce a significant amount of ATP. The electrochemical gradient created by the electron transport chain makes it easier for ATP synthase to manufacture ATP by chemiosmosis.

Detailed explanation-4: -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).

Detailed explanation-5: -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.
