Glycogen is a quizlet.

Glycogen phosphorylase is a special enzyme that cleaves the a (1-4) glycosidic linkage using inorganic phosphate (phosphorolytic cleavage) instead of water. This generates glucose 1-P from the nonreducing end of glycogen. Glycogen phosphorylase cleaves the a (1-4) bonds until it come to about 6 residues to a branch point.
