The Response of Membrane Systems when Exposed to Oscillating Concentration Waves
In network thermodynamics, membranes are described in terms of generalized resistors and capacitors. These reflect the ability of a membrane both to dissipate power and to store chemical energy internally in each local volume during transport processes. For quantitative modelling, the membrane is subdivided conceptually and mathematically into homogeneous ‘lumps’ or slices, each characterized by its own resistance and capacitance. The accuracy of quantitative modelling of diffusion processes depends upon the degree of reticulation of the lumped model; since the model approaches evermore closely to a true continuum of states as the number of lumps (n) is increased. The error is approximately proportional to n−2 .
