WebH is the diffusion coefficient of the proton and (d[H +]/dx) represents the proton concentration gradient over the distance dx. The facilitated component is carried by the facilitating buffer(s) and its calculation (2) is dominated by the diffusion coefficient and concentration of each buffer, (B1, B2, ..., Bn). FJ H = D B1 • (d[B1]/dx) + D B2
