- Question 1: The 4 kinase steps in glycolysis are catalyzed by hexokinase, phosphofructokinase, phosphoglycerate kinase, and pyruvate kinase. Write each of these four reactions, including all participants. i. ii. iii. iv.Question:- 33) Glucose-6-phosphate has different pathways that it can enter in the liver during the fed state. 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: 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 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;…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?Question 1: The overall process enabled by the glyoxylate cycle is: (2acetyl-CoA) + (NAD+) + (2H2O) → (succinate) + (2CoA) + (NADH) + (2H+) Dissect this process further by writing down all of the reactions that are actually involved in making one succinate from two acetyl-CoA units. Show chemical structure for all intermediates.
- QUESTION 22 When the final product of a series of enzymatically-catalyzed reactions binds to the first enzyme in the pathway to limit its production, it generally uses ___ because the structure of this final product is generally not similar to that of any of the enzyme's normal substrates. Allosteric activation Zymogen activation Covalent modification Competitive inhibition Allosteric inhibitionQuestion 9 - Under anaerobic conditions in the muscle, lactate dehydrogenase catalyzes the reaction converting pyruvate to lactate. What is the metabolic reason for this fermentation reaction? It is necessary to reduce pyruvate before it can be converted to acetyl-CoA and enter the citric acid cycle in muscle. NAD* must be replenished for glycolysis to continue. The reaction creates NADH which can produce additional energy in the electron transport chain. O Lactate is more oxidized than pyruvate.Question 29 options: If 6 molecules of acetyl CoA were completely oxidized by the CAC, how many molecules of FADH2 would be produced?
- Question No. 1 Give the advantages and disadvantages of submerged fermentation and solid state fermentation. Give two examples of acetic acid fermentation.QUESTION NO. 1L-Carnitine is synthesized primarily in the liver but also in the kidneys and then transported to other tissues. It is most concentrated in tissues that use fatty acids as their primary fuel, such as skeletal and cardiac muscle.
