Detailed explanation-1: -The mitochondrion performs most cellular oxidations and produces the bulk of the animal cell’s ATP. The mitochondrial matrix contains a large variety of enzymes, including those that convert pyruvate and fatty acids to acetyl CoA and those that oxidize this acetyl CoA to CO2through the citric acid cycle.

Detailed explanation-2: -The mitochondrial matrix is the site of oxidative phosphorylation, where ATP is produced from ADP and Pi by ATP synthase in a mechanism involving the respiratory chain complexes and the proton motive force.

Detailed explanation-3: -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-4: -The inner membrane of the mitochondrion contains the components of the electron transport chain. Oxidation/reduction reactions along the components of the electron transport chain generate a proton gradient that is used by ATP synthase to phosphorylate ADP, thereby producing ATP.

Detailed explanation-5: -Additional metabolites present in the matrix are CO2, H2O, O2, ATP, ADP, and Pi.
