Summary Introduction

To review:

The way through which phosphorylation cascade stimulates synthesis of glycogen.

Introduction:

There are primarily two main types of cell-surface receptors, namely, receptor tyrosine kinases and G-protein-coupled receptors. Receptor tyrosine kinase gets activated when insulin binds to its receptor. As a consequence of binding of insulin to the receptor, a cascade of phosphorylation events takes place, which brings about changes in the activity of several enzymes. These enzymes change the expression of genes.
