Arrange the steps of glycogen degradation in their proper order.
Hormonal signals trigger glycogen breakdown.
Glucose 6-phosphate undergoes further metabolic processing.
Answer Bank
Blocks consisting of three glucosyl residues are moved by remodeling of a-1,4-glycosidic linkages.
Glucose 1-phosphate is cleaved from the nonreducing ends of glycogen and converted to glucose 6-phosphate.
Glycogen is debranched by hydrolysis of a-1,6-glycosidic linkages.
