Question

atp breakdown in cells is accompanied by.
a an increase in potential energy.
b phosphate bonding.
c energy storage.
d a release of energy.

Explanation:

ATP (adenosine - triphosphate) has high - energy phosphate bonds. When it breaks down in cells (hydrolysis), one of the phosphate groups is removed, and the energy stored in the bond is released for cellular processes. It's not about increasing potential energy, phosphate bonding, or energy storage during breakdown.

Answer:

D. a release of energy
