Questions and Answers

What is the key enzyme involved in glycogenesis?

  • Glycogen synthase (correct)
  • Branching enzyme
  • UDP-glucose
  • Tyrosine
  • How is glycogen synthesis initiated?

  • Through the addition of glucose units to reducing ends
  • Through the formation of a 1-6 glycosidic bond
  • By the transfer of glucose from UDP-G to the glycogen PrimerC (correct)
  • By the attachment of glucose at C4 of tyrosine
  • What type of linkage does the branching enzyme form when transferring glucose units?

  • 1-4 linkages
  • 5-8 glucose residues
  • 1-6 glycosidic bonds (correct)
