ATP is considered a high-energy compound because energy is released when a bond is broken between

a. the base adenine and the sugar ribose.

b. the adenosine and the phosphate groups.

c. the base adenine and the phosphate groups.

d. the adenosine diphosphate and the third phosphate.

e. All of the bonds release energy as ATP is completely broken down.

d. the adenosine diphosphate and the third phosphate.

Explanation:

ATP is the most common energetic complex used by cells. The meaning of ATP is adenosine triphosphate.

The energy realized happens when the phosphate gets hydrolysis and that P-O-P bound is a high energy one.

The final result is ADP and phosphate.

This hydrolysis process it's called dephosphorylation.
