When does glycogenolysis occur?

Question

When does glycogenolysis occur?

Answer 1

Glycogenolysis is the breaking down, or catabolism, of the polysaccharide glycogen into molecules of the sugar glucose and molecules of glucose 1-phosphate within the body by enzymes.

Because of the importance of maintaining blood glucose levels,the degredation of glycogen are tightly regulated.In the liver, glycogenolysis accelerates during periods of fasting.In skeletal muscle,glycogen degredation occur duringactive exercise,and accumulation begins as soon as muscle is again at rest.It is regulated by complex series of enzymes and hormones like glycogen phophorylase(enzyme) and hormones like glucagon and epinephrine.

thanx..hope this helps out.

Answer 2

Glycogenolysis transpires in the muscle and liver tissue, where glycogen is stored, as a hormonal response to epinephrine (e.g., adrenergic stimulation) and/or glucagon, a pancreatic peptide triggered by low blood glucose concentrations.

Answer 3

In response to low blood sugar or stress. Usually its slower acting than glucose to raise blood sugar, because more processes of cleavage are used.
