Question 42 4 pts Which of the following best describes the function of the glycogen-branching enzyme? o it cleaves an a(1 ? 6) bond and transfers a block of glucose residues to an interior site via an a(1 ? 4) o it cleaves an a(1 ? 4) bond and transfers a block of glucose residues to an interior site (branch point) via an a(1 ? 6) o none of the answer is correct o it catalyzes the formation of an a(1 ? 4) bond o it cleaves an a(1 ? 6) bond in glycogen

Match the enzymes that degrade glycogen in the left column with the appropriate properties from the right column. More than one answer may be appropriate. a. Phosphorylase b. Ě‘-1,6-Glucosidase c. Transferase 1. Is part of a single polypeptide chain with two activities 2. Cleaves Ě‘-1,4 glucosidic bonds 3. Releases glucose 4. Release glucose-1-phosphate 5. Moves three sugar residues from one chain to another 6. Require ATP

Select all the correct statements. Glycogen phosphorylase: 1. is an enzyme involved in the first step of glycogen utilization. 2. releases glucose-1-phosphate from the non-reducing ends of the molecule. 3. converts glucose to glycogen. 4. removes phosphate from glycogen. 5. catalyzes the phosphorolytic cleavage of the glycosidic linkage in glucose.

A certain cooperative enzyme has four subunits, two of which are bound to substrate. Which of the following statements can be made? A. The affinity of the enzyme for the substrate has just increased. B. The affinity of the enzyme for the substrate has just decreased. C. The affinity of the enzyme for the substrate is at the average for this enzyme class. D. The affinity of the enzyme for the substrate is greater than with one substrate bound.
