Split reins are a piece of equipment used for communicating with a horse while it is being ridden. Split reins are actually two separate, individual reins that are used together, with one rein on each side of the horse's neck.
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.
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.
