Question

1. (02.05 lc) which of the following processes releases energy to be used by a cell? (4 points) a phosphate group is removed from atp to form adp. a phosphate group is added to adp to form atp. a phosphate group is removed from adp to form atp. a phosphate group is added to atp to form adp.

Explanation:

ATP (adenosine - triphosphate) has three phosphate groups. When the cell needs energy, a phosphate - group is removed from ATP through hydrolysis, forming ADP (adenosine - diphosphate) and releasing energy. Adding a phosphate group to ADP forms ATP which stores energy.

Answer:

A. A phosphate group is removed from ATP to form ADP.
