glycogenolysis

(noun)

the production of glucose-1-phosphate by splitting a glucose monomer from glycogen using inorganic phosphate

Examples of glycogenolysis in the following topics:

  • Epinephrine and Norepinephrine

    • Binding to α-adrenergic receptors inhibits insulin secretion by the pancreas, stimulates glycogenolysis (the breakdown of glycogen) in the liver and muscle, and stimulates glycolysis (the metabolic pathway that converts glucose into pyruvate) in muscle. β-Adrenergic receptor binding triggers glucagon secretion in the pancreas, increased adrenocorticotropic hormone (ACTH) secretion by the pituitary gland, and increased lipolysis by adipose tissue.

  • Hormonal Regulation of Metabolism

    • Glucagon raises blood glucose levels, eliciting what is called a hyperglycemic effect, by stimulating the breakdown of glycogen to glucose in skeletal muscle cells and liver cells in a process called glycogenolysis.

  • Carbohydrate Molecules

    • Whenever blood glucose levels decrease, glycogen is broken down to release glucose in a process known as glycogenolysis.
