Question

26. Muscle cells are not able to supply glucose for other tissues because they do not contain which of the following enzymes? a. debranching enzyme b. pyruvate carboxylase c. glucose-6-phosphatase d. phosphoglucomutase e. glycogen phosphorylase 27. Which statement is correct concerning the metabolic reaction shown below? HOCH2 OH a b· c. d· e. The enzyme that catalyzes this reaction is called a mutase. The enzyme that catalyzes this reaction is called a kinase. This reaction requires the free energy of ATP hydrolysis. This reaction occurs only in the kidney. The oxidation level of glucose-1-phosphate is higher than that of glucose-6- phosphate 28. Increased levels of epinephrine in the blood will: a. b. c. d. e. activate adenylate cyclase in liver and muscle cells. stimulate glycogen synthesis. inhibit glycolysis in the muscle cell. stimulate gluconeogenesis in the muscle cell. inhibit the formation of cAMP 29. Which enzyme has an intermediate of the form presented? CH2OPO32 a. Phosphofructokinase b. Glycogen phosphorylase c. Phosphohexose isomerase d. Phosphoglucomutase e. Glucose bisphosphatase OH OH OH
