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.

How many phosphates would ADP have attached to it quizlet?

How many phosphate groups does ADP have? ADP has two groups of phosphate.

How many phosphates are removed from ADP?

ATP (adenosine triphosphate) has three phosphate groups that can be removed by hydrolysis to form ADP (adenosine diphosphate) or AMP (adenosine monophosphate). If there are no phosphates at all, the molecule is referred to as a "nucleoside", rather than a "nucleotide".
