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.
Glycogenolysis is the process of converting the food storage carbohydrate polymer glycogen into glucose for the body to use as energy. Glycogen is a polysaccharide â a long sugar chain â of glucose molecules with side branches. It is a way for animal cells to store excess carbohydrates until needed.
