Which of the Following Has the Highest Energy

Question

Which of the following has the highest energy?
A)ATP
B)ADP
C)AMP
D)A&P

Accepted Answer

ATP (adenosine triphosphate) has more energy than ADP (adenosine diphosphate) or AMP (adenosine monophosphate) because it has three phosphate groups, while ADP has two and AMP has only one. The energy is stored in the bonds between the phosphate groups, so the more phosphate groups, the more energy is stored. "A&P" is not a valid choice as it does not specify a molecule.
