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

Question

Quizplus · Accepted Answer

ATP (adenosine triphosphate) is the primary source of energy for most energy-requiring reactions in cells. When ATP is hydrolyzed (broken down) by the enzyme ATPase, it releases energy and becomes ADP (adenosine diphosphate). The energy released during ATP hydrolysis is used to power many cellular processes, such as muscle contraction, protein synthesis, and active transport of ions across membranes.
