DENDROLOGY

Detailed explanation-1: -The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.

Detailed explanation-2: -The three phosphoryl groups are labeled as alpha (), beta (), and, for the terminal phosphate, gamma ().

Detailed explanation-3: -Answer and Explanation: An ATP molecule contains three phosphate groups.

Detailed explanation-4: -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".

Detailed explanation-5: -ATP stands for adenosine triphosphate. The word triphosphate indicates that the molecule has 3 phosphate groups. ATP stores energy within the bonds between phosphate groups, especially the second and third.
