- 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 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 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: 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 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). Use these values to compute the standard free energy of hydrolysis (releasing Pi) of i. glucose 6-P ii. fructose 1,6-bis-P iii. 1,3-bisphosphoglycerate iv. phosphoenolpyruvate Part b: Which of these four compounds is the strongest phosphoryl donor?______________ Which is the weakest?__________________ Part c: The phosphoglycerate kinase reaction is favorable by -18.9 kJ/mol in the glycolytic direction, as stated above. 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 1 a. John has just taken his Lunch meal, after which he is going to takes his Daily soccer practice match in the next 30 min, how will glycolysis operate/work in such conditions or be applicable b.

Enzymes are critical in the metabolism of most most organic compounds, actually 30% of reactions are catalysed by them. How would the inactive enzymes (Sickness) in electron Transport Chain compromise the fat breakdown in the body.
- 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. Put away your notes and text and draw the complete Calvin-Benson cycle starting from 3molecules of Ru1,5BP. Show stoichiometry along the way using 6 GAP molecules to regeneratethe 3 Ru1,5BPs. Label each reaction according to its enzyme class (your choices arecarboxylase, kinase, dehydrogenase, aldolase, epimerase, isomerase, phosphatase, andtransketolase – see the posted enzyme guide for help on this).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?
