Question

A molecule of ATP contains adenine, ribose, and three phosphate groups. The bond between the last two phosphates is easily broken, resulting in a molecule of ADP and one phosphate group. If the bond between the second and third phosphate groups were more stable, what would be the most likely consequence?
Answer
A. More energy would be required to break the bond, so the net energy produced would be less.
B. Once the bond between the phosphate groups is broken the net energy released would increase.
C. The bond between the first and second phosphates would have to be broken to produce energy.

Answer 1

I think the correct answer from the choices listed above is option A. Most likely, the consequence of this would be that more energy would be required to break the bond, so the net energy produced would be less. Hope this answers the question.

Answer 2

Answer:

A. More energy would be required to break the bond, so the net energy produced would be less.

Explanation:

Since the bond between the second and third phosphate groups are more stable more energy would be required to break them. The net energy produced would be less as some of it is getting consumed to break the stronger bond between the second and third phosphate groups.

In cells ADP (adenosine diphosphate) is easily converted to AMP (adenosine monophosphate with the release of energy and inorganic phosphate.

ADP --> AMP + Pi + energy
