GENERAL HISTOLOGY

Detailed explanation-1: -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. This is a complex reaction powered by the proton gradient across the mitochondrial inner membrane, which is generated by mitochondrial respiration.

Detailed explanation-3: -However, the majority of the reactions that produce ATP happen within the mitochondria (in eukaryotic cells; Figure 13.2. 1). During these reactions, electron carriers are created and oxygen pulls the electrons through an electron transport chain to create ATP, which powers cellular activity.
