The main function of mitochondria is the production of energy during the production of adenosine triphosphate (ATP) via the TCA Cycle (which is also as the Krebs Cycle and the Citric Acid Cycle).That process is an important metabolic pathway (see also what is metabolism).ccording to many textbooks: Energy production within cells is the main function of mitochondria. However, some students are told not to state that mitochondria produce or create energy. Strictly, the energy is released from storage (in chemical bonds) by reactions that occur in mitochondria.
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell. Cells that need a lot of energy, like muscle cells, can contain thousands of mitochondria. Apart from cellular respiration, mitochondria also play a key role in the ageing process as well as in the onset of degenerative disease. The powerhouse function When the breakdown products from the digestion of food find their way into the cell, a series of chemical reactions occur in the cytoplasm.
