what role does adp/atp play in living cells
Adenosine diphosphate Adenosine diphosphate (ADP), also known as adenosine pyrophosphate (APP), is an important organic compound in metabolism and is essential to the flow of energy in living cells. ADP consists of three important structural components: a sugar backbone attached to adenine and two phosphate groups bonded to the 5 carbon atom of ribose. The diphosphate group of ADP is attachted to the 5’ carbon of the sugar backbone, while the adenosine attaches to the 1’ carbon.[1]
