Definitions. 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.
What is Glycogen? Glycogen is a polysaccharide of glucose that serves as a form of energy storage in fungi and animals. The polysaccharide structure of glucose shows the primary storage form of glucose in the body. Glycogen is made and stored in the cells of liver and muscles that are hydrated with the four parts of water. It acts as the secondary long-term energy storage. Muscle glycogen is quickly converted into glucose by muscle cells and liver glycogen that converts into glucose for use throughout the body which includes the central nervous system.
Some glucose is used to form the more complex carbohydrate cellulose, the main structural component of plant cell walls. Some is used to provide immediate energy to plant cells. The rest is changed to a different chemical form, usually starch, and stored in seeds, roots, or fruits for later use.lycogen is the form in which glucose is stored in the liver and muscles of animals for energy needs. Muscle glycogen is used primarily to fuel muscle contractions (such as during exercise). Liver glycogen is used to restore glucose to the blood when the sugar level is low (such as between meals).
