Chapter 14, Problem 25CQ

Summary Introduction

To explain: Whether the magnitude of the free energy change for the ATP hydrolysis increases or decreases, as the pH increases from 5 to 6.

Concept introduction: ATP contains an adenine moiety to which 3 phosphoryl groups that are linked by a phosphodiester bond are followed by two phosphoanhydride bonds. The hydrolysis of ATP releases chemical energy that has been stored in the high-energy phosphoanhydride bonds.
