The Equilibrium Potential of a Given Ion Across a Membrane

Multiple Choice

The equilibrium potential of a given ion across a membrane is

A) A function of the concentration of that ion on both sides of the membrane
B) The potential at which there is no net movement of that ion across the membrane
C) The potential difference across the membrane that creates an electric force favoring diffusion of the ion in one direction that is equal in magnitude and opposite in direction to the diffusion force provided by the concentration difference of the ion across the membrane
D) Both a function of the concentration of that ion on both sides of the membrane and the potential at which there is no net movement of that ion across the membrane are correct
E) All of the choices are correct
