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 multibranched polysaccharide of glucose that serves as a form of energy storage in animals and fungi. The polysaccharide structure represents the main storage form of glucose in the body.In humans, glycogen is made and stored primarily in the cells of the liver and the muscles hydrated with three or four parts of water.lycogen forms an energy reserve that can be quickly mobilized to meet a sudden need for glucose, but one that is less compact than the energy reserves of triglycerides (lipids). In the liver, glycogen can compose from 5 to 6% of its fresh weight (100â120 g in an adult).
