Detailed explanation-1: -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-2: -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-3: -The process of forming ATP from the electron transport chain is known as oxidative phosphorylation. Electrons carried by NADH + H+ and FADH2 are transferred to oxygen via a series of electron carriers, and ATPs are formed.

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: -In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.
