Chapter 8.3, Problem 2CC

Summary Introduction

To determine: In which of the following there is more free energy present $\text{Glutamic}\text{acid}\text{+}\text{Ammonia}\text{+}\text{ATP}$ and $$ $\text{Glutamine}\text{+}\text{ADP}\text{+}$Ⓟi and also explain the answer.

Introduction: The reaction between $\text{Glutamic}\text{acid}\text{+}\text{Ammonia}\text{+}\text{ATP}$ gives the product that is $\text{Glutamine}\text{+}\text{ADP}\text{+}{\text{P}}_{\text{i}}$.

The free energy is more in the first reaction as the $\text{ΔG}$ is negative for this coupled reaction.
