Identify the true statements regarding α‑1,6 linkages in glycogen.

(a) branching increases glycogen solubility.
(b) new α‑1,6 linkages can only form if the branch has a free reducing end.
(c) the number of sites for enzyme action on a glycogen molecule is increased through α‑1,6 linkages.
(d) exactly seven residues extend from these linkages.
(e) the reaction that forms α‑1,6 linkages is catalyzed by a branching enzym

(A) Branching increases glycogen solubility.

(B) New α‑1,6 linkages can only form if the branch has a free reducing end.

(C) The number of sites for enzyme action on a glycogen molecule is increased through α‑1,6 linkages.

E) The reaction that forms α‑1,6 linkages is catalyzed by a branching enzym

first one is the correct answer

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
