MICROANATOMY

Detailed explanation-1: -Most of the adenosine triphosphate (ATP) synthesized during glucose metabolism is produced in the mitochondria through oxidative phosphorylation . This is a complex reaction powered by the proton gradient across the mitochondrial inner membrane, which is generated by mitochondrial respiration.

Detailed explanation-2: -The majority of ATP synthesis occurs in cellular respiration within the mitochondrial matrix: generating approximately thirty-two ATP molecules per molecule of glucose that is oxidized.

Detailed explanation-3: -Mitochondria oxidize respiratory substrates and produce ATP in response to the demand imposed by ATP-consuming reactions in the cytosol.
