ATP synthesis is the formation of adenosine triphosphate through the interaction of the ATP synthase enzyme with cellular material. The ATP synthase enzyme binds adenosine biphosphate with inorganic phosphate to produce ATP. ATP is the basic unit of energy that enables the cells of most living organisms to function.
ATP production generally occurs in the mitochondria of cells. ATP enables cells to function by acting as an energy transfer mechanism that transfers chemical energy into cell functions, such as respiration, metabolism and cellular division. It is also utilized in the assembly of cellular proteins and is responsible for the production of DNA and RNA, the genetic material necessary for reproduction.
