Detailed explanation-1: -Most of the ATP produced during aerobic cellular respiration is produced via substrate-level phosphorylation .

Detailed explanation-2: -Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. The energy released is used to create a chemiosmotic potential by pumping protons across a membrane. This potential is then used to drive ATP synthase and produce ATP from ADP and a phosphate group.

Detailed explanation-3: -Oxidative phosphorylation produces 24–28 ATP molecules from the Kreb’s cycle from one molecule of glucose converted into pyruvate.

Detailed explanation-4: -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-5: -Oxidative phosphorylation is an ATP generating process, which takes place in the inner membrane of mitochondria of aerobic organisms. In a generic sense, this process generates ATP via transferring electrons from FADH2 or NADH via a series of complex carriers.
