What is "glycogenolysis"

n. (context biochemistry English) The production of glucose-1-phosphate by splitting a glucose monomer from glycogen using inorganic phosphate

Glycogenolysis is the breakdown of glycogen (n) to glucose-6-phosphate and glycogen (n-1). Glycogen branches are catabolized by the sequential removal of glucose monomers via phosphorolysis, by the enzyme glycogen phosphorylase.
