Effect of membrane crowding on encounter rates. Evolution of the encounter rate for lipid-soluble molecules with surface occupancy for several obstacles' different distance scales. The gray triangles and diamonds correspond as in Fig. 5 B to distances of 0.2 and 2.0 obstacle diameters, the dashed lines are guides for the eye, and the solid black line is calculated from the linear fit to the long-distance relative diffusion coefficient.
