Chapter 28, Problem 2P

Interpretation Introduction

Interpretation:

Glycogen can be synthesized in the body by the same enzymes that degrade it. The reason for this process to be utilized in glycogen synthesis only to a small extent, while most glycogen biosynthesis occurs via a different synthetic pathway should be explained.

Concept Introduction:

Phosphorylase enzyme is used to catalyze the glucose molecules in the cell. It results in the formation of glucose unit by cleavage. The equilibrium equation is represented as follows:

${\left(\text{Glucose}\right)}_{\text{n}}+\text{Pi}\stackrel{\text{phosphorylase}}{\rightleftharpoons }{\left(\text{Glucose}\right)}_{\text{n-1}}+\text{Glucose-1-phosphate}$
