A theoretical discussion of the decomposition rate constants of enzyme substrate complexes is presented, based upon an enzyme model published earlier (Damjanovich & Somogyi,1973). These rate constants are expressed by the aid of molecular parameters characteristic for the enzyme-substrate complexes and the molecules in the surrounding liquid phase. Both the exponential and pre-exponential factors of the expressions describing the composition rate constants contain parameters depending on the mass distribution of the reaction mixture in a specific way which is characteristic for the enzyme-substrate complex. The findings suggest a new kind of the enzyme regulation generated by the surrounding medium.
