NADH is still produced. Which of the following glycolytic metabolites will not be detectable in a cell that is exposed to arsenate? a. Glucose 6-phosphate b. Fructose 6-phosphate c. 1,3-bisphosphoglycerate d. 3-phosphoglycerate c. 2-phosphoglycerate I8- Which of the following do you think will be the energy account of glycolysis for a cell exposed to arsenate? a. A net gain of 2ATP and 2NADH b. A net gain of IATP and 2NADH c. A net gain of 2NADH and zero ATP d. A net gain of 2NADH and a loss of IATP e. None of the above. 19- When you compare the catabolism of a saturated fatty acid to that of an unsaturated fatty acid of squal length, which of the following will you expect to be different? a. b. c. d. e. The number of rounds of beta-oxidation required for the breakdown. The number of acetyl CoA units produced during the breakdown. The number of NADH molecules produced during the breakdown. The number of FADH2 molecules produced during the breakdown. All of the above.Explanation / Answer
13. Ethanol and CO2 are the final products of fermentation.
14. CO2 and Water are the final products of aerobic respiration.
15. Pyruvate carboxylase.
16. None of the above mentioned enzyme is common to glycolysis and gluconeogenesis. The enzyme which is common to both process is 3-phosphoglycerate kinase.
17.1,3 bisphosphoglycerate would not be detected because 1-arseno- 3-phosphoglycerate would be formed.
18. C a net gain of 2 NADH and zero ATP because after the incorporation of arsenate no ATP is formed and hence not net ATP production.
19. The number of rounds of beta oxidation required for the break down.
