Description: The principal glycogen stores in vertebrates are in skeletal muscle and liver. Breakdown of these stores into usable energy, or mobilization of glycogen, involves sequential phosphorolytic cleavages of bonds, catalyzed by glycogen phosphorylase. In plants, starch is similarly mobilized by the action of starch phosphorylase . Both reactions release glucose-1-phosphate from nonreducing ends of the glucose polymer.
