DENDROLOGY

Detailed explanation-1: -Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. 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: -If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell.

Detailed explanation-3: -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. This bond is a source of potential chemical energy, and it’s kind of like a compressed spring.
