Unformatted text preview: 1 FINAL EXAM, Biochemistry 102/2002______________________ I. Fill in all of the enzyme catalyzed reactions which convert the substrate on the left to the product on the right. Draw the correct structure for each intermediate molecule. Include the names or abbreviations of any other reactants and products (e.g., ATP, ADP, P i , NAD + , NADH, etc.), and any required prosthetic groups (e.g., TPP, FAD, biotin, etc.). acetyl CoA (cytosol) O CH 3 CH 2 CH 2 CSACP Briefly describe the function of the acyl carrier protein in the reactions catalyzed by fatty acid synthase and name the coenzyme from which the prosthetic group of ACP is derived. 2 II. Fill in all of the enzyme catalyzed reactions which convert the substrate on the left to the product on the right. Draw the correct structure for each intermediate molecule. Include the names or abbreviations of any other reactants and products (e.g., ATP, ADP, P i , NAD + , NADH, etc.), and any required prosthetic groups (e.g., TPP, FAD, biotin, etc.). Pyruvate in the mitochondrial matrix of a liver cell Glucose Indicate which enzymatic reactions above are different from the reactions used in glycolysis. 3 III. Fill in all of the enzyme catalyzed reactions which convert the substrate on the left to the product on the right. Draw the correct structure for each intermediate molecule. Include the names or abbreviations of any other reactants and products (e.g., ATP, ADP, P i , NAD + , NADH, etc.), and any required prosthetic groups (e.g., TPP, FAD, biotin, etc.). (A) Acetyl CoA (draw) Isopentenyl pyrophosphate (draw) ---------------------------------------------------------------------------------------------------------------------------------- B. Acetyl CoA (matrix) Acetyl CoA (cytosol) ________________________________________________________________________________________ 4 IV. Outline the steps starting with an increase in adenylate cyclase activity in the liver and ending with the relevant changes indicated below. Use arrows ( or )to show the effect at each step, as in the lecture handout . (A) Changes in the activities of Glycogenolysis and Glycogen Synthesis (liver) Blood [Glucose] Blood [Glucagon] Adenylate Cyclase Activity ? (B) Changes in the activities of Gluconeogenesis and Glycolysis (liver) Blood [Glucose] Blood [Glucagon] Adenylate Cyclase Activity ? 5 V. Answer 2 of the 3 questions below. Be sure to cross out the choice that you do not wish to have graded, or well cross out choice C for you. (A) Show the complete mechanism of the Rubisco catalyzed reaction of ribulose 1,5 bisphosphate and CO2 to yield 3 phosphoglycerate, at the level presented in lecture....
