In the atp cycle, a phosphate group is cut off of atp to form adp, absorbing energy. atp to form adp, releasing energy. adp to form atp, absorbing energy. adp to form atp, releasing energy.

the answer here is, "ATP to form ADP, releasing energy." hope this helped!

ATP to form ADP, releasing energy.

Explanation:

Adenosine triphosphate (ATP) is the energy currency of the cell because the energy is stored in its bond. When the terminal phosphate group is removed by hydrolysing ATP in the presence of ATPase enzyme, ATP is converted to adenosine diphosphate (ADP), inorganic phosphate (pi) and energy. Thus, on removal of phosphate group from ATP, ADP is formed and releases energy.
