Electron transport chain. The enzyme succinate dehydrogenase is part of the citric acid cycle (Fig. 17.15) and the electron transport chain (Fig. 18.6). Calculate the free energy (ΔG) of the reaction catalyzed by succinate dehydrogenase under physiological conditions: 2 mM succinate, 0.5 mM fumarate, 2 mM FAD, and 0.2 mM FADH2. [Recall that ΔG = -n F ΔEo. See Table 18.1 for the relevant standard reduction potential (ΔEo).]
