Functions of the mitochondria

Mitochondrial function

Matrix

Krebs cycle

Mitochondrial protein synthesis

β-oxidation of fatty acids

Inner membrane

ATP synthesis

Respiratory chain

The main function of the mitochondria is to obtain energy, although each mitochondrial component has a different function:

The fact that mitochondrial compartments have different enzyme complexes implies that different functions will be carried out in each of them:

Mitochondria in sperm and cardiac cells

Mitochondria are the predominant organelles in sperm because they produce the large amount of energy they need to travel to the egg.

Heart cells also have many mitochondria, as they need to produce a lot of ATP to be used in the contraction and movement of the heart.
