- Question 1: When the CAC is run in reverse by microorganisms that use it to fix carbon, the citrate synthase reaction is different and is catalyzed by an enzyme called ATP-citrate lyase. Write the reaction catalyzed by ATP-citrate lyase, then briefly (in one sentence) explain why the use of different chemistry (different from the ‘normal’ direction) makes sense here.QUESTION 26 During gluconeogenesis, whereby liver cells convert pyruvate to glucose, Fructose-6-phosphate (F6P) is converted to Glucose-6-phosphate (G6P). If the standard equilibrium concentrations are: [F6P] = 0.52 M and [G6P] = 1.48 M, then Keq’ is ______ and the reaction is ________. Fructose-6-P ó Glucose-6-P > 1; exergonic > 1; endergonic < 1; exergonic < 1; endergonicQuestion 1: In some microorganisms, carbon fixation occurs by reversal of the citric acid cycle. This reversal is accomplished in part by the use of a strong reductant (ferredoxin) to drive the alpha-ketoglutarate dehydrogenase reaction in the reductive direction. Part a: ΔG°‘ for reaction as it occurs in the ‘normal’ (oxidative) citric acid cycle is -30.1 kJ/mol. The standard reduction potential for NADH is -0.32 V. In order to drive the reaction in the reverse direction, the reductant (a ferredoxin) must have a lower reduction potential than NADH/NAD+. Remembering that this is a two-electron reduction, and using the numbers given just above, compute the value of the ferredoxin reduction potential that would be needed to make the standard free energy zero (so that the reductive reaction is enegetically just as favorable as the oxidative reaction). Assume that all of the other reactants are the same in the reductive as in the oxidative reaction. Write out the steps in your calculation;…

All of the following are possible except OA.) it is oxidized to acetyl CoA for fatty acid biosynthesis O B). it can enter the pathway for glycogen biosynthesis O c.) it is a substrate for glucose-6-phosphatase OD. )it is oxidized in glycolysis to provide energy for the bodyQuestion 1: Part a: Assume that the standard free energy of ATP hydrolysis is -31 kJ/mol. Assume the following values for the standard free energy changes of the four reactions: HK -16.7 kJ/mol; PFK -14.2 kJ/mol; PGK -18.9 kJ/mol; PK -31.7 kJ/mol. (from bio.libretexts.org).

In gluconeogenesis, this step is simply reversed; i.e. it is not one of the three steps in gluconeogenesis that is driven by using different chemistry than that of glycolysis. How can this be? (Be specific: what specific factors could enable reversal of this step?)Question 29 options: If 6 molecules of acetyl CoA were completely oxidized by the CAC, how many molecules of FADH2 would be produced?
- Question 1: Cytochrome c oxidase actually conserves energy not just by pumping protons from the matrix to cytosol but also by consuming protons from the matrix in production of water. If consumption of a matrix proton has a similar effect on the gradient as pumping a proton (not strictly true but a fair place to start), what would the efficiency of energy conservation be?QUESTION 47 The role of oxygen gas in our cells is to accept electrons that come from NADH. produce CO2. react with glucose to split water. catalyze reactions in glycolysis. breakdown ATP.Question 1: ATP synthases contains 3 copies of each of the large subunits (called α and β in the E. coli enzyme). The number of c subunits can vary among different ATP synthases, ranging from 8 to 17. Part a: Briefly explain how this variation in the number of c subunits would affect the energetics of ATP synthesis. For a fixed value of the protonmotive force, how much energy can the gradient provide to drive one revolution of the ATP synthase, in a synthase with 8 c- subunits versus a synthase with 17 c-subunits?
