Which statement MOST COMPLETELY EXPLAINS the large ΔG° for the hydrolysis of phosphoenolpyruvate?
A) Hydrolysis of the phosphate 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.
E) The large ΔG° of the phosphoester bond.

Question

Quizplus · Accepted Answer

The large ΔG° for the hydrolysis of phosphoenolpyruvate is most completely explained by the hydrolysis of the phosphate bond along with the conversion of the enol to the keto form of pyruvate. This process releases a significant amount of energy, contributing to the high ΔG°.
