Chemical potentials and channel open probabilities An alternative way to think of the probability of gating of membrane-bound channels is to think of the membrane as consisting of two species of channel, closed and open, at concentrations celosed and copen, respectively. These two species are subject to constant interconversion characterized by an equilibrium in which their respective chemical potentials are equal. By setting the chemical potentials for these two species equal, work out an expression for the open probability.
