How is Atp Formed?

ATP, adenosine triphosphate, is a complex molecule used as an energy source by all living organisms that contains the nucleoside adenosine and three phosphates on its tail. The recycling of ATP, which consists of removing one of the phosphates and reattaching it, occurs in the mitochondria of each cell. The ultimate source of energy for building ATP is food, the body only has about 50 grams of ATP which needs to be recycled constantly. The average 2,500 calories a day will contribute to the turnover of 400lbs of ATP.
