- Based on your knowledge of the structure of NAD+ and an assumption that coenzyme dissociation is the rate limiting step of the alcohol dehydrogenase mechanism, hypothesize why a N249W mutation at the coenzyme binding site would increase the rate of catalysis.Can someone help with this question? L-Malate + NAD⁺ ← → Oxaloacetate + NADH Above is what i selected for the equation, but I don't know how to find the equilibrium constant.The metabolic reactions and enzymes that require NAD/NADH are shown in Figure 1. However, it is not specified whether oxidized or reduced NAD is used in each reaction, nor what form of NAD is produced as a product. Add this specificity to the attached figure. You are also welcome to draw your own figure.
- Most biochemists agree that the most accurate number of H+ needed to generate one ASP is blank. Therefore one NADH generated about blank ATP molecules?Choose the correct answer from the options in brackets. The [positive/negative] standard free‑energy change favors the oxidation of succinate by covalently‑bound FAD. This is consistent with K′eq [ >1 / =1 / <1 ]. Oxidation by NAD+ would require a large, [positive/negative] standard free‑energy change, with K′eq favoring the synthesis of succinate.Substrate cycling does not violate the laws of thermodynamics in making both directions of a reaction favorable (i,e Step 3 glycolysis). How is this so? Explain
- Can someone help with this question? L-Malate + NAD⁺ ← → Oxaloacetate + NADH Above is what i selected for the equation, but I don't know how to find ΔE'৹.The coenzymes NAD and FAD can “shuttle” hydrogens from one reaction to another. How does this process serve to couple oxidation and reduction reactions?Which of the following statements is true for the shown reaction?
