Explanation a) The activation of glycogen phosphorylase is done by epinephrine. GTP-binding protein is activated when binding of glucagon with a specific receptor on hepatocyte takes place. This triggers the concentration of cAMP . As a result, cAMP -dependent protein kinase gets activated, which proceeds the cascade of phosphorylation. This activates phosphorylase b kinase and hence glycogen phosphorylase is activated, which results in the breakdown of glycogen. b) The activation of glycogen synthase is done by epinephrine. GTP-binding protein is activated when binding of glucagon with a specific receptor on hepatocyte takes place. This triggers the concentration of cAMP . As a result, cAMP -dependent protein kinase gets activated, which proceeds the cascade of phosphorylation...

Proteins

We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains t…

Protein Expression

The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry…

Question

Chapter 24, Problem 40RE

Interpretation Introduction

Interpretation:

The effect of epinephrine on the given enzymes is to be discussed.

Concept Introduction:

The chemical messengers that pass information from the source to the target are called hormones.

A molecule that acts as a bridge between the hormone and the target is called the second messenger.

The hormones that principally control carbohydrate metabolism are epinephrine, glucagon, and insulin.
