Which statement best describes how the energy stored in atp is released to drive biochemical reactions? a. energy is released when the ribose sugar reacts with oxygen during aerobic respiration. b. energy is released when adenine is removed from ribose by dehydration synthesis. c. energy is released when a phosphate group is removed by hydrolysis.

C. ATP uses phosphate groups - When it only has 2 phosphate groups, it is ADP, when it has 3, it is ATP, and can release that 3rd phosphate gorup. When it releases it, it is ADP again and can get another Phosphate group, become ATP again, and go give that energy to where it is needed in the cell.

This process is repeated indefinitely to power the cell.

Active transport. now that i answered your question i wish you can me
