Question

which one is a high - energy bond in an atp molecule?
the bond attaching adenine to ribose
the bond attaching the third phosphate group
the bond attaching the first phosphate group
need help? review these concept resources.

Explanation:

ATP (adenosine - triphosphate) has high - energy phospho - anhydride bonds between its phosphate groups. The bond attaching the third phosphate group is a high - energy bond. When this bond is hydrolyzed, a large amount of energy is released. The bond attaching adenine to ribose is not a high - energy bond, and the first phosphate group bond is not as high - energy as the one of the third phosphate group.

Answer:

The bond attaching the third phosphate group
