Which Is FALSE About the Equilibrium Potential of a Given

question 41

Multiple Choice

Which is FALSE about the equilibrium potential of a given ion across a membrane?

• A) It is a function of the concentration of that ion on both sides of the membrane.
• B) It is the potential at which there is no net movement of that ion across the membrane.
• C) It is the potential difference across the membrane at which an electric force favoring movement of the ion in one direction is equal in magnitude and opposite in direction to the diffusion force provided by the concentration difference of the ion across the membrane.
• D) A permeable ion will move in the direction that will tend to bring the membrane potential toward that ion's equilibrium potential.
• E) An anion that is in higher concentration inside the cell than outside the cell will have a negative eqilibrium potential.
