Question

Consider a neuron in which the Cl- concentration inside of the cell is 15 mM and outside of the cell is 140 mM. Once the ions flow and reach an equilibrium, approximately what will be the concentration of Cl- inside of the cell

    Answer:

    The correct answer is – negative.

    Explanation:

    Cl- ion is more concentrated outside of the cell, as it is given 140 and therefore it will try to move to the inside of the given cell as inside ion concentration is low.

    At last, the diffusive force will be get to equilibrium due to an electrostatic force pulling Cl- ions back out of the cell. At this equilibrium point, Cl- ions will moved towards to the the neuron and cause the membrane potential to be more negative.
