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 the analogue of starch, a glucose polymer that functions as energy storage in plants. It has a similar structure to amylopectin (a component of starch), but is more extensively branched and compact than starch.ue to the way glycogen is synthesised, every glycogen granule has at its core a glycogenin protein. Glycogen in muscle, liver, and fat cells is stored in a hydrated form, composed of three or four parts of water per part of glycogen associated with 0.45 millimoles of potassium per gram of glycogen.
