Gidentify the true statements regarding α-1,6 linkages in glycogen. at least four glucose residues separate α‑1,6 linkages. the number of sites for enzyme action on a glycogen molecule is increased through α‑1,6 linkages. new α‑1,6 linkages can only form if the branch has a free reducing end. the reaction that forms α-1,6 linkages is catalyzed by a branching enzyme. exactly four residues extend from these linkages.

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
