The role of the enzyme in the succinate-enzyme-fumarate equilibrium


The following is an account of an investigation into the role of the enzyme in the succinate-enzyme-fumarate equilibrium. The method consisted in the comparison of the value of the free energy change in this reaction obtained from oxidation-reduction potentials, with that calculated from the entropies and other physicochemical properties of succinic acid and fumaric acid.
