6. In glycogen utilization, debranching enzyme is an alpha 1,6 hydrolase AND a: a. phosphorylase. b. transglycosidase. c. dehydrogenase. d. glycosidase. e. oxidase. 7. The major immediate product of glycogen breakdown is: 8. Phosphorylase kinase phosphorylates glycogen synthase make it: 9.Which of the following is not true of the reaction catalyzed by the pyruvate dehydrogenase complex? c The reaction occurs in the mitochondrial matrix. 10. Glucose labeled with C in C-3 and C-4 is completely converted to acetyl-CoA via glycolysis and the 14 pyruvate dehydrogenase complex. What percentage of the acetyl-CoA molecules formed will be labeled with C, and in which position of the acetyl moiety will the C label be found? 14 14 a. 100% of the acetyl-CoA will be labeled at C-1 (carboxyl). b. 100% of the acetyl-CoA will be labeled at C-2. c. 50% of the acetyl-CoA will be labeled, all at C-2 (methyl). d. No label will be found in the acetyl-CoA. e. Not enough information is given to answer this question. 11. Malonate is a competitive inhibitor of succinate dehydrogenase. If malonate is added to a mitochondrial preparation that is oxidizing pyruvate as a substrate, which of the following compounds would you expect to decrease in concentration?
