® ADP has one more phosphate group and can store more energy.
© ADP has one more phosphate group and stores less energy.
O ADP has one less phosphate group and stores less energy.

Answer 1

The correct answer is: ADP has one less phosphate group and stores less energy.

Step-by-step explanation:

• ATP: Adenosine Triphosphate. It possesses three phosphates groups linked together by two phosphoanhydride bonds.
• ADP: Adenosine Diphosphate. It possesses two phosphate groups linked together by one phosphoanhydride bond.
• ATP or ADP stores energy in the form of their phosphoanhydride bonds (bond between two phosphate groups).
• ADP possess one phosphoanhydride bond while ATP possess two phosphoanhydride bonds, so ADP stores less energy than ATP.
