Summary Introduction

To determine: The overall ∆G value when it is coupled to ATP hydrolysis (ΔG =+3.4 kcal/mol) and whether the process is endergonic or exergonic.

The reaction is glumate+NH3glutamine

Introduction: The full form of ATP is adenosine triphosphate, which acts as both a precursor for RNA and is known as the energy currency of the cell. The ATP is known as energy currency because the hydrolysis of ATP generates energy and power most of the endergonic reactions.

Explanation of Solution

A molecule of ATP is made up of small components such as 5-carbon sugar, ribose, which act as a framework that attaches the other subunits; another component is adenine, and triphosphate is the third component which represents a chain of three phosphates. A chemical reaction, a change in free energy, occurs known as ∆G or delta G.

The ∆G of the product (glutamine) is 3.4 kcal/mol, while the free energy released during hydrolysis of ATP is ΔG =-7.3kcal/mol; hence the overall ∆G will be the sum of these values which is –3.9kcal/mol. And therefore, the ∆G is a negative value which indicates that the process is exergonic.
