Why is glycogen debranching enzyme necessary? a) It allows regulation of the rate of glycogenolysis. b) Because glycogen phosphorylase cannot convert G1P to G6P. c) Because the substrate binding cleft of glycogen phosphorylase cannot accommodate chains of glycogen closer than 4-5 residues away from a branch. d) It accelerates glycogen breakdown because it operates faster than glycogen phosphorylase.
