How Does Glycogen Phosphorylase Catalyze Reactions?
Glycogen phosphorylase catalyzes the cleavage of α-1,4-glycosidic bonds in glycogen by adding an inorganic phosphate (Pi) to the terminal glucose unit. This reaction produces glucose-1-phosphate, which can then be converted into glucose-6-phosphate for subsequent use in glycolysis or gluconeogenesis.
