Chapter 17, Problem 51RE

Interpretation Introduction

Interpretation:

The positive $\Delta \text{G}°$ values of the four reactions in glycolysis are to be explained.

Concept introduction:

The glycolysis of glucose takes place in ten steps, out of which four have positive $\Delta {\text{G}}^{°}$ values and six steps have negative $\Delta {\text{G}}^{°}$ values.

If the value of free energy is negative, the reaction is said to be exergonic and if the value is positive, the reaction is endergonic.
