Description: A Structure of ATP. B After ATP loses one phosphate group, the nucleotide is ADP (adenosine diphosphate); after losing two phosphate groups, it is AMP (adenosine monophosphate). c ATP forms by endergonic reactions that phosphorylate ADP. ADP forms again when a phosphate group from ATP is used to phosphorylate another molecule. Energy from such transfers drives endergonic reactions that are the stuff of cellular work.
