ANATOMY

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: -Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria.

Detailed explanation-3: -The inner membrane of mitochondria is rather complex in structure. It has many folds that form a layered structure called cristae, and this helps in increasing the surface area inside the organelle. The cristae and the proteins of the inner membrane aid in the production of ATP molecules.

Detailed explanation-4: -Most of the energy derived from oxidative metabolism is then produced by the process of oxidative phosphorylation (discussed in detail in the next section), which takes place in the inner mitochondrial membrane.

Detailed explanation-5: -Mitochondria: Turning Food Into Energy. Mitochondria are the powerhouses of the cell. They break down nutrients and, through a sort of “assembly-line, ” produce energy in the form of substance called adenosine triphosphate (ATP). ATP can then be used by the cell whenever energy is required.
