IX, and [X], are the concentrations of ionic species X, outside and inside the cell, respectively (A). (20 pts.) You have a cell that has contains only K and Na leak channels in the membrane (no voltage-gated channels). The ionic flows (currents, arbitrary units) through these K' and Na' leak channels are represented in the figure below, as a function of membrane potential. lonic flow (current) flow -40 -20 +20 +60 +80 potential Imvl Nat flow (1) On the figure, mark the approximate values of the membrane potential that correspond to the resting potential of the cell, and to the equilibrium potentials of Na and K ions.

Explanation / Answer

1) From the diagram, the equilibrium potential of potassium is -60 mV and the equilbrium potential of sodium is -60 mV. Since, the membrane is permeable to only sodium and potassium ions, the resting membrane potential is 0.
