Question

When a cell demands energy, ATP loses which phosphate group?

  1. First 
  2. Second 
  3. Third 
  4. Fourth 

hintHint:

  • Energy is releasable in the bond between second and third phosphate groups.

The correct answer is: Third


    Third
    • When a cell demands energy, ATP lose third phosphate group .

    • As ATP provides readily releasable energy in the bond between the second and third phosphate groups, it loses third phosphate group to release energy.
