Chapter 21, Problem 27P

Interpretation Introduction

Interpretation:

A balance equation that showing the effect of simultaneous activation of glycogen phosphorylase and glycogen synthase including the reaction catalyzed by phosphoglucomutase and UPD-glucose pyrophosphorylase should be written.

Concept introduction:

Enzyme phosphoglucomutase breakdown glycogen into glucose 6-phosphate.

The enzyme phosphoglucomutase converts glucose 6-phosphate into glucose 1-phosphate.

glucose 1-phosphate reacts with UTP (Uridine-5’-triphosphate) to form UDP − glucose.

UDP − glucose act as the substrate of the glycogen synthesis process.
