Which statement MOST COMPLETELY EXPLAINS the large delta G d

Which statement MOST COMPLETELY EXPLAINS the large delta G\' degree for the hydrolysis of phosphoenolpyruvate (PEP)? Hydrolysis of the phosphoanhydride bond along with the conversion of the enol to the keto form of pyruvate. The hydrolysis of the phosphoanhydride bond. Conversion from the enol to the keto form of pyruvate. Strong bond energy along with a change in the stereochemistry of the molecule. The large delta G degree of the phosphoester bond.

Solution

The correct answer is : A.Hydrolysis of the phosphoanhydride bond along with the conversion of the enol to the keto form of pyruvate.

Reason:Phosphoanhydride bonds are formed by either splitting of water between two phosphoric acids or between a carboxylic acid and a phosphoric acid.These bonds tend to have a large negative delta G of hydrolysis.
