Detailed explanation-1: -Definition. Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Detailed explanation-2: -Most of the adenosine triphosphate (ATP) synthesized during glucose metabolism is produced in the mitochondria through oxidative phosphorylation.
Detailed explanation-3: -The chemical reactions takes place in mitochondria is Oxidative phosphorylation and it happens inside the mitochondria. It is a process of conversion of oxygen to water. It comprises an enzymatic series of electron donor and acceptors which releases energy.
Detailed explanation-4: -Mitochondria are the major site of oxidative metabolism, and hence ATP synthesis, in eukaryotic cells. Thus, whereas the glycolytic metabolism of glucose generates 2 ATP molecules, 36–38 are generated by the reactions of the citrate cycle and the oxidation of the resulting NADH and FADH2 by the respiratory chain [1].
