Question

Which of the following could result from having few or no ?-1,6 linkages in glycogen? Select all that apply.

1. Glycogen degradation would slow down.

2. Glycogen synthesis would be faster.

3. Glycogen solubility would increase.

4. Maintaining proper blood sugar levels would be more difficult.

Answer 1

The correct answer is 1 glycogen degradation would slow down.

Step-by-step explanation:

Glycogen is the principle storage polysaccharide present in the liver and muscle of human body.

Glycogen contain both alpha-1,4-glycosidic linkage and alpha -1,6-glycosidic linkage.During glycogenolysis some glucose residues are transferred from branch point of the glycogen to its end and thereafter a single glucose residue is linked to the branch point of glycogen by alpha-1,6-glycosidic linkage.

The alpha-1,6-glycosidic linked glucose of glycogen is finally get separated from glycogen by the catalytic activity of alpha-1,6-glycosidase enzyme in the final step of glycogenolysis.

According to the given question if there is no alpha-1,6-glycosidic linkage in the glycogen then glycogen degradation will slow down.
