Which statement best explains the large ∆G° for the hydrolysis of phosphoenolpyruvate?
A)hydrolysis of the phosphoanhydride bond along with the conversion of the enol to the keto form of pyruvate
B)the hydrolysis of the phosphoanhydride bond
C)conversion from the enol to the keto form of pyruvate
D)strong bond energy along with a change in the stereochemistry of the molecule

Question

Quizplus · Accepted Answer

The large ∆G° for the hydrolysis of phosphoenolpyruvate is due to the hydrolysis of the phosphoanhydride bond, which is a high-energy bond. Additionally, the conversion of the enol to the keto form of pyruvate also requires energy. Therefore, the hydrolysis of the phosphoanhydride bond along with the conversion of the enol to the keto form of pyruvate results in a large ∆G° value for this reaction.
