Mitochondria causes maximum cell’s supply of ATP and their quantity within a cell is simply associated with metabolic activity. Cellular respiration is performed out of the mitochondria. Mitochondrial matrix composed of variety of enzymes that play a major part in metabolic pathway. These involve carbohydrate, lipid, amino acids, urea & heme biosynthesis.

Mitochondrial morphology is controlled by balancing active absorption of water & active secretion by mitochondrion. Hence, mitochondria swell in__________.
