2C. A “pulse-chase" experiment using "C-labeled glucose can be carried out on a yeast extract that is maintained under strictly anaerobic conditions. The experiment consists of incubating a small amount of "C-labeled substrate (the pulse) with the yeast extract just long enough for each intermediate in the fermentation pathway to become labeled. The label is then “chased" through the pathway by the addition of excess unlabeled glucose. The chase effectively prevents any further entry of labeled glucose into the pathway. 2 ADP 2 ATP Glucose ---> CH3 2 NAD* 2 NADH 2 Pyruvate H H H-C-OH C=0 CH3 CH3 2 co, 2 Ethanol 2 Acetylaldehyde (1) If [1-"C]glucose (glucose labeled at C-1 with "C) is used as a substrate, will there be any "C in the product (ii) Lactic acid is the final fermentation product in vertebrates, while ethanol is the final fermentation product in yeast. Lactic acid can be converted back into glucose while ethanol can not be. In the space below, use a thermodynamic rationale to…

2. Enzyme-catalyzed reactions. Answer the following with true or false. If false, explain why. (a) The initial rate of an enzyme-catalyzed reaction is independent of substrate concentration. (b) At saturating levels of substrate, the rate of an enzyme-catalyzed reaction is proportional to the enzyme concentration. (c) The Michaelis constant Km equals the substrate concentration at which velocity (v) = Vmax/2. (d) The Km for a regulatory enzyme varies with enzyme concentration. (e) If enough substrate is added, the normal Vmax of an enzyme-catalyzed reaction can be attained even in the presence of a noncompetitive inhibitor. (f) The Km of some enzymes may be altered by the presence of metabolites structurally unrelated to the substrate. (g) The rate of an enzyme-catalyzed reaction in the presence of a rate-limiting concentration of substrate decreases with time. (h) The sigmoidal shape of the v versus [S] curve for some regulatory enzymes indicates that affinity of the enzyme for the…

CELLULAR RESPIRATION AND FERMENTATION Name: Date: Instructor: Section/Group: POST-LAB QUESTIONS 1. Both cellular respiration and fermentation ordinarily begin with which molecule? ves 2. What role does cellular respiration play in the metabolism of an organism? 3. Glucose breakdown results in the breaking of C-H bonds and stored energy is released. Compare and contrast the end products of fermentation and cellular respiration in terms of their energy produced. 4. Fermentation results in the net production of only 2 ATP, while cellular respiration results in the production of at least 36 ATP. Explain these results with reference to the end products of both of these processes. Cellular Respiration and Fermentation 93

1, For EACH of the following enzyme categories, (1) describe what the general function of the enzyme is; (2) identify a SPECIFIC enzyme in glycolysis that performs this function; and (3) identify the names of the organic substrate and product for the specific enzyme identified. Remember that the name of the category need not appear in the actual name of the enzyme. A. First enzyme category: kinase (answer (1), (2), and (3) B. Second enzyme category: dehydrogenase (answer (1), (2), and (3) C. Third enzyme category: isomerase (answer (1), (2), and (3)
3. Explain the total (net) yield of ATP from Aerobic respiration in three of the different stages of cellular respiration (Glycolysis, Krebs Cycle and Electron Transport Chain). Pyruvate oxidation or the Link reactions does not make ATP. In other words, how many total ATP energy molecules are produced in each cycle and which steps in the different cycles make the ATP. Explain the yield in reference to the overall cellular respiration Equation.
