Detailed explanation-1: -Adenosine diphosphate (ADP) carries two phosphate molecules.

Detailed explanation-2: -ADP or adenosine diphosphate is composed of one adenine molecule, a ribose sugar and two phosphate groups.

Detailed explanation-3: -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 attached to the 5’ carbon of the sugar backbone, while the adenine attaches to the 1’ carbon.

Detailed explanation-4: -ADP, the “uncharged” version of the molecule, stands for adenosine diphosphate. The word diphosphate indicates that the molecule has 2 phosphate (PO3) groups.

Detailed explanation-5: -ATP is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate groups. These three phosphate groups are linked to one another by two high-energy bonds called phosphoanhydride bonds.
