44. Which of the following statements about glycogen synthesis is incorrect?
(A) The initiation of glycogen synthesis is the attachment of the first glucose tothe OH group of a tyrosine on a protein named glycogenin.
(B) A chain of about seven c(1→4) linked glucose molecules are typicallyformed by glycogenin.
(C) Glycogen synthase uses UDP-glucose as a substrate and transfers theglucosyl residue onto the non-reducing end of the glycogen chain.
(D) Branches of glycogen are made by an amylo-transglycosylase that catalyzesthe transfer of a string of seven a(1→4) linked glucosyl units of a glycogenchain to the C-2 position on a glucose of the same or a neighboring glycogenchain.
(E) UDP-glucose is synthesized from UTP and glucose-I-phosphate by enzymeglucose-1-phosphate uridylyltransferase.
