- 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.arrow_forwardUsing the data in this table, what is the AG° (in KJ/mol) for the reduction of FAD by water?arrow_forwardIn full detail, describe the function of NAD+ and FAD.

- 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.arrow_forwardComplete an enlargement of part of the thylakoid membrane in the beaker with the solution at pH 8.
