WebGlycogen metabolism consists of two phases: a constructive phase in which glycogen synthesis occurs, and a degradative phase, known as glycogenolysis, in which the polysaccharide is catabolized. Glycogenolysis releases glucose when it is needed. In the liver, glycogen is a glucose reserve for the maintenance of normal blood glucose levels, … WebWhen less glucose is available, the reverse combination of enzyme stimulation and inhibition occurs, and net breakdown of glycogen to glucose 6-phosphate (glycogenolysis) ensues. Two paths are available to this glucose 6-phospahte: (1) In most cells, including skeletal muscle, it enters the glycolytic pathway
