Detailed explanation-1: -Only oxidative phosphorylation uses oxygen directly, but the other two stages can’t run without oxidative phosphorylation.
Detailed explanation-2: -Stage 3–Electron Transport Chain In the final stage of cellular respiration, oxygen combines with the electrons and protons to form water.
Detailed explanation-3: -Oxygen sits at the end of the electron transport chain, where it accepts electrons and picks up protons to form water.
Detailed explanation-4: -Oxygen is the terminal electron acceptor in the mitochondrial electron transport chain and therefore is required for the generation of energy through oxidative phosphorylation.
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.
