What molecule is formed from the breaking off of a phosphate group from ATP?

• A. Adenosine Triphosphate (ATP)
• B. Adenosine Diphosphate (ADP)
• C. Cyclic Adenosine Monophosphate (cAMP)
• D. Dephosphorylated ATP

Answer: (B)

When a phosphate group is removed from adenosine triphosphate (ATP) during a reaction known as hydrolysis, the result is the formation of adenosine diphosphate (ADP). This reaction involves the cleavage of one of the high-energy phosphate bonds in ATP, which releases energy that can be used for cellular processes. ATP is composed of three phosphate groups, and when one of these phosphate groups is cleaved off, it transforms ATP into ADP, which then contains only two phosphate groups. This process is a fundamental part of energy metabolism in cells, as ATP serves as the primary energy currency, and its conversion to ADP represents a transfer of energy. ADP can be recycled back into ATP through the addition of a phosphate group during cellular respiration or photosynthesis, illustrating the dynamic balance and cycle of energy utilization and storage within biological systems.
