glycogen metabolism is the terminology used for both glycogen synthesis and glycogen degradation ,glycogenesis and glycogenolysis .both of these pathways are exactly opposite to each other because both of these pathways involve different enzymes
glycogenesis is carried out by enzymes HEXOKINASE,PHOSPHOGLUCOMUTASE,UDP-GLUCOSE-PYROPHOSPHORYLASE,and GLYCOGEN SYNTHASE.
glycogenolysis is carried out by enzymes GLYCOGEN PHOSPHORYLASE,PHOSPHOGLUCOMUTASE,and debranching enzyme (GLUCAN TRANSFERASE).

What function does glycogen have in living things?
Glycogen is a stored sugar that is made available as the first energy source while exercising. It lasts for about 20 minutes. Then the body uses other sources of metabolism for energy. Glycogen is stored in the liver.
What is an insilin?
A polypeptide hormone secreted by the islets of Langerhans and functioning in the regulation of the metabolism of carbohydrates and fats, especially the conversion of glucose to glycogen, which lowers the blood glucose level.
What is the smallest polysaccharide?
glycogen
Can glycogen be converted?
No. Insulin converts glucose into glycogen for storage in the body. Glucagon converts glycogen into glucose. (it's the various cells in the body that do the conversion in either case, insulin and glucagon are hormones that induce the shift in the metabolism.)
What is the function of glycogen granules in animal cell?
Glycogen granules form an energy or food store in mammalian cells. When needed, the glycogen can be broken down (hydrolysed) into glucose, which is used in respiration as a source of energy for the cell. For some background see: http://www.sciencedaily.com/articles/g/glycogen.htm
What are the three enzymes involved in the conversion of glycogen to glucose?
The process of "glycogenolysis" is the splitting of glycogen in the liver, which in turn produces glucose. Glucagon can be administered in emergency diabetic situations where sugar can't be taken orally.

Discuss the role of epinephrine on carbohydrate metabolism?
It is generally accepted that epinephrine promotes the breakdown of muscle glycogen to lactic acid and that this lactic acid is largely reconverted to glycogen by the liver.
Which of the following enzymes is not required to breakdown glycogen into glucose-6-phosphate molecules for further metabolism?
All of these enzymes are necessary in the breakdown of glycogen into glucose-6-phosphate molecules.
What are glycogen storage diseases?
Glycogen Storage disease is an inhearited disease that is caused by the large amount of build up of a carbohydrate called glycogen in the cells of the body. Unfourtantly when the build up occures then it causes other organs of the body to malfunction such at the liver.
What organelle does Pompe disease affect in a cell?
It is the only glycogen storage disease with a defect in lysosomal metabolism, and the first glycogen storage disease to be identified, in 1932 by the Dutch pathologist J.C.Pompe.The build-up of glycogen causes progressive muscle weakness throughout the body.

What is an insilin?
A polypeptide hormone secreted by the islets of Langerhans and functioning in the regulation of the metabolism of carbohydrates and fats, especially the conversion of glucose to glycogen, which lowers the blood glucose level.
What is the smallest polysaccharide?
glycogen
What is the importance of heat during metabolism?
the entropy we experience as heat from the combustion reactions of glycogen is technically a metabolic waste. It isn't required, it's there because the burning of glycogen (glucose as the body stores it for use) is an exothermic reaction, hense it creates heat, like burning wood, or gasoline.
What stimulates cell metabolism?
Spices such as chiles, cinnamon, giner and caffine, tea are thought to stimulate metabolism. Normally digestion of sugars stored in tissues as glycogen begin when there is in need of energy. During starvation (or severe exercise) fats starts burning to make energy.
