Mitochondria are well-defined cytoplasmic organelles of the cell which take part in a variety of cellular metabolic functions. Survival of the cells requires energy to perform different functions.The mitochondria are important as the fact that these organelles supply all the necessary biological energy of the cell, and they obtain this energy by oxidizing the substrates of the Krebs cycle.unctions of Mitochondria. The most prominent function of mitochondria is to produce energy to the cell in the form of ATP through oxidative respiration process. It also regulates the metabolic activity of the cell.
