2. Which of the following statements regarding ATP is true? (A) the energy of hydrolysis is the same for all of the phosphate groups of the molecule (B) despite the very exergonic nature of the hydrolysis, ATP does not hydrolyze spontaneously due to a very high activation energy (C) the AG of hydrolysis within the cell is substantially greater than the AGo' due to a higher concentration of ATP with respect to ADP (D) electrostatic attraction of the phosphate groups contributes to a more exergonic free energy (E) both b and c are correct
