Geographic Concepts. The Census Bureauâs urban-rural classification is fundamentally a delineation of geographical areas, identifying both individual urban areas and the rural areas of the nation.
Glycogen is a polysaccharide molecule stored in animal cells along with water and used as a source of energy. When broken down in the body, it is transformed into glucose, an important source of energy for animals. In animals, it plays a role similar to that played by starch in plants.
Glycogen is a storage form of glucose and is a ready source of energy. It is important in liver and muscle. The glycogen in muscle is used as a fuel reserve for ATP synthesis while in the liver it is used as a glucose reserve for the maintenance of blood glucose.Muscle glycogen does not help maintain blood glucose levels, as liver glycogen does.Muscle glycogen is used as a source of energy during increased muscle activity.xplain the differences of glycogenolysis in muscle and liver. The glycogen in muscle is used as a fuel reserve for ATP synthesis while in the liver it is used as a glucose reserve for the maintenance of blood glucose. Muscle glycogen does not help maintain blood glucose levels, as liver glycogen does.
