The effect of diffusion, electric transport and convection on heterogeneous enzyme catalysis]

The consideration of electric and volume transport additionally to diffusion leads to the dependence of concentration profiles in heterogeneous enzyme catalysis on additional parameters (e. g. electrical field strength, convection velocity) which are valuable for influencing and optimizing these systems. For autocatalysis the local periodic concentration profiles are influenced essentially by these phenomena (change of onset and wavelength). When diffusion is negligible equations are given to determine the kinetic parameters vmax and KM from transport measurements.
