The energy that cells need to function is

Adenosine triphosphate, or ATP, is the primary carrier of energy in cells.

Explanation:

The water-mediated reaction known as hydrolysis releases energy from the chemical bonds in ATP to fuel cellular processes. adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things.

the answer is

c. parental
