3. GLYCOGEN METABOLISM Glycogen is a polysaccharide that is the principal storage form of glucose in animal/human cells. Glycogen metabolism is synthesis and break down of glycogen. It is a very large, branched polymer of glucose residues that can be break down to yield glucose molecules when energy is needed. The pathway for the synthesis and degradation of glycogen is not reversible.

4. GLYCOGENESIS DEFINITION : The synthesis of glycogen from glucose is called glycogenesis. LOCATION : Cytosol of Liver and Muscle cell. REQUIREMENTS : ATP ( Adenosine triphosphate), UTP ( Uridine triphosphate), Glucose.

5. GLYCOGENESIS PATHWAY

6. GLYCOGENOLYSIS DEFINITION : The break down or degradation of stored glycogen into glucose is called glycogenesis. Glycogen is degraded by breaking alpha 1,4-bonds and alpha 1,6- bonds glycosidic bond. LOCATION : Cytosol of Liver and Muscle cell.
