Most cellular work is accomplished by energizing molecules by them.

Answer;

ATP

Phosphorylation

Most cellular work is accomplished by ATP energizing molecules by phosphorylating them.

Explanation;When a cell uses chemical energy to perform work, it uses the energy released from an exergonic reaction to drive a endergonic reactionPhosphorylation involves the transfer of a phosphate group to a molecule or compound. ATP is a molecule that provides energy for body cells to carry out their functions, such as transport, movement of muscles. Cells obtain energy from ATP, through hydrolysis of ATP molecules. The energy released from the hydrolysis of ATP into ADP is used to perform cellular work.
