As discussed above, mitochondria are the sites of respiration, and generate chemical energy in the form of ATP by metabolizing sugars, fats, and other chemical fuels with the assistance of molecular oxygen.
A cell may contain a few hundreds to five one hundred thousand mitochondria. Function: They help in cellular respiration. Food is oxidized in the mitochondria and energy is produced in the form of ATP (Adenosine triphosphate).Mitochondria are, therefore,popularly known as the power house of the cell.
