- 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: 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: 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 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 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. In this regard, L-carnitine plays an important role in energy production by conjugating to fatty acids for transport from the cytosol into the mitochondria. L-carnitine shuttle is an example of A. ion driven active transport B. facilitated diffusion C. simple diffusion D. ATP driven active transportE. symport F. antiportQUESTION NO.2 Statements: (1) Glucose is both a hexose and a aldose. (2) There can never be more than three enantiomers for a molecule. (3) All common disaccharides have beta-one-four linkages. Which statements are true?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: 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 94 Most of the CO2 from the catabolism of glucose is released during _____. electron transport chemiosmosis glycolysis the citric acid cycleQuestion 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 21 You are in charge of generating a scaffold for use in tissue engineering applications that behaves similarly to the natural ECM proteins. What proteins might you want to include in your scaffold? A Fibronectin only B Collagen, fibronectin, and proteoglycans C Proteoglycans only D None of the above are proteins in the ECM E Collagens onlyQuestion 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 5 Match the given choices below with the correct question/ description. Which is known as β-D-glucopyranose?
