Membrane diffusion the simplest kind of transport is the unassisted diffusion of solutes across membranes (see figure 1a) the kinds of molecules that transit in this fashion are more soluble in oil than water and so readily dissolve in and then spontaneously traverse the nonpolar lipid core of the membrane bilayer.
