Column 2 was obtained assuming a diffusion constant of 2000 μm² s⁻¹ for all species. For realistic diffusion coefficients, we arrived at the numbers of columns 3–8. For every radius, the first column gives the concentrations near the center of the cell and the second one those near the membrane boundary. The concentrations are given in μM, the flux in μM s⁻¹.
