B)ADP
C)AMP
D)cyclic AMP
E)GTP

Question

Quizplus · Accepted Answer

The hydrolysis of ATP (adenosine triphosphate) is a major source of energy for most energy-requiring reactions in the cells of the body. When ATP is hydrolyzed, it releases the stored energy in its phosphate bonds which can then be used by the cell for various processes. ADP (adenosine diphosphate) and AMP (adenosine monophosphate) are also involved in cellular energy metabolism, but ATP is the primary energy currency of the cell. Cyclic AMP (cAMP) and GTP (guanosine triphosphate) are involved in signaling pathways within the cell.
