The first step involved in glycogenolysis is?

A) Splitting glucose molecules from the branched glycogen molecule by dehydrogenation

B) The formation of fructose-6-phosphate

C) The splitting of glucose molecule from the branched glycogen molecule by phosphorylation

D) A and C

E) B and C

Solution

Splitting glucose molecules from the branched glycogen molecule by dehydrogenation and by phosphorolysis. Glycogen is broken down and the debrancing enzyme breaks the branch glycosidic bond.

The process involves breaking up of 1 4 glycosidic followed by breaking the 1 6 glycosidic link at the branching point and release free glucose.
