The most important function of the mitochondria is to produce
energy in the form of ATP molecules. This
entire process is known as oxidative phosphorylation.
important to maintain proper concentration of calcium ions within the
various compartments of the cell. Mitochondria help the cells to achieve
this goal by serving as storage tanks of calcium ions.
They also help in the building of certain parts of the blood, and hormones like testosterone and estrogen.
Mitochondria in the liver cells have enzymes that detoxify ammonia and hence takes part in detoxification.
They play an important role in the process of programmed cell death.
Unwanted and excess cells are pruned away during the development of an
organism. The process is known as apoptosis. Abnormal cell death due to
mitochondrial dysfunction can affect the function of organ.
