You have obtained the following table that gives the biochemical standard free energy change (AG" ) , for each step of the citric acid cycle. The final reaction, which is the regeneration of oxaloacetate from the oxidation of malate_ missing its AG"_ Reaction acetyl e CoA + oxaloacetate + HzO citrate + CoA +Ht citrate cis-aconitate + HzO = isocitrate isocitrate + NAD+ a- ~ketoglutarate + COz NADH 0- ketoglutarate + NAD+ + CoA =succinyl CoA + COz + NADH succiny] CoA + P; + ADP = succinate + ATP + CoA succinate + FAD = fumarate + FADH2 fumarale + HzO = L~malate L-malate + NAD+ oxaloacetate + NADH + Ht 31.4 +6.3 8.4 30.1 3.3 -3.8 n.d. You set up an experiment under biochemical standard conditions whereby malate dehydrogenase and free Mg2+ are mixed with the reagents L-malate, NAD+_ oxaloacetate, and NADH. You monitor the concentration of the reagents until they reach equilibrium: The final concentrations are given in the table. L-Malate 1.995 M NAD+ 1.995 M Oxaloacetate 4.98 X 10-3 M NADH 4.98 X 10-3 M Give the standard free energy change for the reaction.
