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 ΔG of hydrolysis within the cell is substantially greater than the ΔG°′ 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

Question

Quizplus · Accepted Answer

Despite being a very exergonic reaction, ATP hydrolysis does not occur spontaneously because it has a high activation energy barrier that must be overcome.
