Imagine a scenario in which a negatively charged ion, Ion A-, is more concentrated on the outside of the cell membrane, yet is at electrochemical equilibrium (i. e., there is no net ion flux across the membrane, even though the membrane is permeable to Ion A-). Which of the following must be true in order for this scenario to be true?
a. The inside of the cell must be negatively charged relative to the outside of the cell (a negative Vm).
b. The inside of the cell must be positively charged relative to the outside of the cell (a positive Vm).
c. Ion A- must be only slightly negatively charged. Ion A- must be extremely negatively charged.
d. This scenario is impossible.
