网易日记>班主任之友Glucose phosphorylation during glycogenolysis is the phosphorylation reaction of a substrate level during glycogenolysis. This phosphorylation reaction is catalyzed by the enzyme glycogen phosphorylase, and it converts glucose-1-phosphate (one of the two phosphorylated products of glycogenolysis) into glucose-6-phosphate. Glycogen phosphorylase is activated by the presence of phosphorylated proteins and covalently attached phosphate (PO4) ions. Glucose-6-phosphate serves as the substrate for glycolysis and is the starting point for the breakdown of glucose. The overall reaction in phosphorolysis is as follows: Glucose-1-phosphate + ATP → Glucose-6-phosphate + ADP
