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.
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
