    Let’s consider an electrical current through a single ion channel, as shown in the following figure. We start by treating an ion channel as a cylindrical pore through the cell membrane. The channel is of length L ≈ 5 nm and is filled with water. The concentration difference of Na+ ions across the channel is Δc ≈ 100 mM. This concentration difference produces a flux of ions through the channel given by DΔc/L, where D is the diffusion constant for...
