The reaction catalyzed by malate dehydrogenase, Malate + NAD. oxaloacetate + NADH + H, has a G"value of +29.7 kJ-mol spontaneously in a cell? (5 points) (b) How does the citrate synthase reaction (described above) promote the malate dehydrogenase Il change in free energy for the two reactions? (5 points) In a cell this reaction will not occur spontaneously because the Gor is positive at STP. The citrate synthase reaction promotes the malate dehydrogenase reaction because the malate produces oxaloacetate which then gets used in the citrate reaction. Since this is constantly being used up, it keeps the reaction continues because the malate will continue to form oxaloacetate. The overall change in free energy is 61.2 kJ/mol. nt of oxaloacetate low, which is why the Multiple Choice- 5 points each 6. If the G10 of the reaction A B is-40 kJ/mol, under standard conditions the reaction: A) is at equilibrium. B) will never reach equilibrium. C) will not occur spontaneously. D) will proceed at a rapid rate. E) will proceed spontaneously from A to B.Explanation / Answer
