Detailed explanation-1: -1: The third stage of cellular respiration uses the energy stored during the earlier stages in NADH and FADH2 to make ATP. Electron transport chains embedded in the mitochondrial inner membrane capture high-energy electrons from the carrier molecules and use them to concentrate hydrogen ions in the intermembrane space.

Detailed explanation-2: -Step 3: ATP synthesis by chemiosmosis. The enzyme ATP synthase catalyzes ATP synthesis.

Detailed explanation-3: -The third and final stage of cellular respiration, called electron transport, takes place on the inner membrane of the mitochondrion. Electrons are transported from molecule to molecule down an electron-transport chain.

Detailed explanation-4: -There are three main stages of cellular respiration: glycolysis, the citric acid cycle, and electron transport/oxidative phosphorylation.
