Questions and Answers

What is the main function of a protein that cleaves the alpha 1-4 glycosidic bond of glycogen?

  • Cleaves the alpha 1-2 glycosidic bond of glycogen to remove the branch
  • Cleaves the beta 1-4 glycosidic bond of glycogen to remove the branch
  • Cleaves the alpha 1-4 glycosidic bond of glycogen to remove the branch (correct)
  • Cleaves the alpha 1-6 glycosidic bond of glycogen to remove the branch

How is ATP synthesis in the electron transport chain achieved?

  • The passage of electrons through a transmembrane protein which mediates the addition of one inorganic phosphate to adenosine diphosphate
