Answer:
C. activates compounds for some reactions by transferring a phosphate group.
Explanation:
Adenosine triphosphate, also known as ATP, is an energy carrier molecule used by the cells of living organisms to carry out their cellular function. ATP has the peculiar ability to store and release energy needed to do work. This energy is stored when a phosphate molecule is added to ADP to form ATP while it is released when the last phosphate group is removed to form ADP.
ATP supplies energy to compounds by transferring one of its phosphate molecules to it in a process called PHOSPHORYLATION. This transfer causes the compound to be activated for the cellular process it is about to undergo.
