Detailed explanation-1: -It is the respiratory cycle that is responsible for production of large quantities of ATP and consumption of oxygen. In addition, the respiratory cycle converts NADH and FADH2 into reactants that the Krebs cycle requires to function.

Detailed explanation-2: -Oxidative phosphorylation is the process where energy is harnessed through a series of protein complexes embedded in the inner-membrane of mitochondria (called the electron transport chain and ATP synthase) to create ATP.

Detailed explanation-3: -The Krebs Cycle generates ATP and many energized electrons (in the form of FADH2 and NADH) for the electron transport chain.

Detailed explanation-4: -Electron transport is the final stage of aerobic respiration. In this stage, energy from NADH and FADH2 is transferred to ATP. During electron transport, energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space.

Detailed explanation-5: -The citric acid cycle, which makes the most NADH.
