In cells especially those in the liver, glucose molecules are bonded together to form glycogen. Why?

Expert Solution

Like Plants store glucose in the form of Starch,In Humans,Cells store Glucose in the form of Glycogen .Glucose is need for the Production of energy (ATP) in humans for performing of cellular functions or activities.This ATP is produced from Glucose by the process of Glycolysis,Where glucose is converted into Pyruvate where there is a net release of 2 ATP.

So the Use of glucose for the prodcution of energy depends on the demand for ATP.When the body have Enough ATP and Large amount of Glucose in the blood,These glucose are bonded to form Glycogen especially in the Liver cells by the process of Glycogenesis.

This process of Glycogenesis(Conversion of Glucose into Glycogen) is Stimulated by the Release of Insulin in response to high blood glucose level from the Beta cells of Islets of Langherhans of Pancreas.Whenever Glucose is need for the Production of energy,if there is no enough glucose in Blood. These glycogen are converted back into Glucose by the process of Glycogenolysis.This is Stimulated by Hormoned Glucagon release from alpha cells of Islets of Langherhans of Pancreas.

This Conversion in the storing of Glucose in the form of Glycogen & Release of Glucose from Glycogen whenever Needed also prevents Hyperglycemia(Increased concentration of Glucose in the Blood).

Hyperglycemia can cause-

1.Headaches.

2.Blurred vision.

3.Increased thirst.

4.Frequent peeing.

5.Fatigue etc

Glycogen is the body’s storage form of glucose. When glycogen is degraded, glucose 1-P is formed. Glucose 1-P can then be isomerized to glucose 6-P. Starting with glucose 1-P and ending with two molecules of pyruvate, what is the net yield of glycolysis in terms of ATP and NADH formed?

Describe how glucose-6-phosphate formed by glycogen breakdown in the liver converts to glucose by glucose-6-phosphatase and how the newly formed glucose leaves the liver cells. Describe why this process allows for separation from glycolysis.

1. Liver metabolism during prolonged fasting. A) What happens when your glucose stored as liver glycogen is gone. What options does the liver have to provide fuel to the brain? B) During starvation muscle tissue is at first used, but then there is a shift to another fuel source. This saves muscle tissue necessary for life (such as muscles of the diaphragm needed for breathing). What is this alternative fuel source?

Glucagon serves to increase blood glucose concentrations by releasing glucose stored in liver cells into the blood. What is the function of its antagonist, insulin? a. to increase blood glucose levels b. to decrease blood glucose levels c. to increase blood sodium levels d. to increase blood calcium levels

Unlike liver cells, muscle cells do not secrete glucose into the blood. What about glucose-6-P prevents its secretion and how do liver cells overcome this problem? McArdle’s disease (also called glycogen storage disease V) is a genetic disorder in which muscle cannot make functional phosphorylase. Speculate as to why McArdle’s patients show muscle fatigue (tiredness) with even moderate exercise. McArdle’s disease is inherited as a recessive trait. Consider the activity of the phosphorylase enzyme and suggest an explanation for the...
