Magnesium ion (Mg⁺⁺) forms complexes with ATP. What would happen to the stability of ATP if the magnesium was removed? A) There would be no change in stability B) The ATP would be more stable C) The ATP would be less stable D) The effect on stability would depend on specific conditions E) Either A or B is correct

Question

Magnesium ions stabilize ATP by neutralizing the negative charges of the phosphate groups, making ATP less likely to hydrolyze. Removing magnesium would decrease this stabilization, making ATP less stable.
