<u>Answer:</u>
ATP or the Adenosine Triphosphate is the energy currency of the living world, which transfers energy from one organic molecule to other, even from one cell organelle to other.
<u>Explanation:</u>
The functional group of ATP is phosphate which is quite evident from its name.
Adenosine diphosphate is the parent molecule. During either photophosphorylation or the respiration, the Inorganic phosphate molecule that is present in the cellular fluid gets attached to the parent molecule ADP via a high energy bond which is broken to give energy to the normal reactions.
