ATP- adenosine triphosphate

Respiration results in the formation of ATP (adenosine triphosphate) through a process called the Krebs cycle which takes place on the membranes of the mitochondrion. ATP is the form of energy used in the body and provides cells with all the energy needed to carry out their daily functions such as drive metabolic reactions which must occur fast enough if life is to be sustained. If there is an excess of ATP then this will be stored in the mitochondrion for later use.
