Why is mitochondria called powerhouse of the cell?
Mitochondriaare known as the powerhouse of cells. Mitochondria create energy for the cell, and this process of creating energy for the cell is known as cellular respiration. Most chemical reactions involved in cellular respiration occur in the mitochondria. The energy required for various chemical activities needed for life is released by the mitochondria in the form of ATP (Adenosine triphosphate) molecules. For this reason, mitochondria are known as the powerhouse of cells.
We know respiration results in the chemical reactions involving oxidation of food and release of energy. Since mitochondria facilitate these reactions and help in the release of energy, they are therefore known as "power house of the cell". Since mitochondria carry out an important function of plant and animal cells, they are present in both.
