A theoretical model is presented for describing a previously untreated effect of viscosity on the apparent decomposition rate of enzyme-ligand complexes. Since the translational diffusion is hindered by the viscosity, its increased value results in an enlarged portion of ligands which can be rebound by the enzyme immediately after the dissociation of the complex. The model accounts for the experimentally observed decrease in maximal velocity of enzymic reactions at high viscosity. At the same time, it serves as a tool to obtain new information about the energetic processes of enzyme action.
