- Question: A. To explore the consequences of coupling ATP hydrolysis under physiological conditions to a thermodynamically unfavorable biochemical reaction, consider the hypothetical transformation X⟶Y, for which Δ?′°=20.0 kJ/mol. What is the ratio of [Y]/[X][Y]/[X] at equilibrium? B. Suppose XX and YY participate in a sequence of reactions during which ATP is hydrolyzed to ADP and Pi. The overall reaction is X+ATP+H2O⟶Y+ADP+Pi Calculate [Y]/[X] for this reaction at equilibrium. Assume that the temperature is 25.0 °C and the equilibrium concentrations of ATP, ADP, and Pi are 1.00 M each. C. We know that [ATP], [ADP], and [Pi] are not 1.00 M under physiological conditions. Calculate [Y]/[X] for the ATP‑coupled reaction when the values of [ATP], [ADP], and [Pi] are those found in rat myocytes. Metabolite Concentration in rat myocytes (M) ATP 8.05x10-3 ADP 0.93x10-3 Pi 8.05x10-3Question 29 options: If 6 molecules of acetyl CoA were completely oxidized by the CAC, how many molecules of FADH2 would be produced?QUESTION 1 Using the free energy values of glycolysis and pyruvate transformation to ethanol calculate free energy (in kJ/mol) of glucose fermentation to ethanol: Glucose + 2 ADP + 2 Pi ⇌ 2 Ethanol + 2CO2 + 2 ATP + 2 H2O

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 6 Give a diagrammatic representation of fatty acid synthase complex and discuss the regulation of fatty acid synthesis.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. How will oxidative phosphorylation work in sickly John who usually practice daily in soccer? Make possible scenarios c. 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.
- Nearly all organisms on Earth carry out some form of glycolysis. How does this fact support or not support the assertion that glycolysis is one of the oldest metabolic pathways?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: Fumerase is an enzyme in the citric acid cycle that catalyzes the conversion of fumerate to L-malate. Given the fumerate (substrate) concentrations and initial velocities below, construct a Lineweaver-Burk plot and determine Vmax and Km values for the fumerase catalyzed reaction. Fumerate (mM) Rate (mmol l-1 min-1) 2.0 2.5 3.3 3.1 5.0 3.6 10.0 4.2 Fumerase has a molecular weight of 194,000 and is composed of four identical subunits, each with an active site. If the enzyme concentration is 1 x 10-8 M for the experiment in part (a), calculate kcat value for the reaction of fumerase with fumerate. Note: units for kcat are reciprocal seconds (s-1).
- 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: In glycolysis one glucose ( a 6 carbon molecule) is broken down into 2 pyruvate molecules ( each 3 carbon molecules). this process occurs in two separate reactions. A particular toxin, charchuin, found in poison slugs, targets one of these reactions and renders the carbons in that particular pyruvate radioactive and thus, unstable. Predict how Charchuin would impact the amount of products produced in the Krebs cycle. provide reasoning to support your response.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;…
