Question

What enzyme exposes a single glucose residue joined by an a-1,6-glycosidic linkage? O transferase O glycogen phosphorylase O phosphoglucomutase O 0-1,6-glucosidase O hexokinase

Answer 1

Glycogen branching enzyme 1 (GBE1) plays an essential role in glycogen biosynthesis by generating α-1,6-glucosidic branches from α-1,4-linked glucose chains, to increase solubility of the glycogen polymer
