Explanation / Answer

The greater permeability of K+ through leak channels maintains the resting membrane potentials at a value near the eqilibrium potential for this ion

At the resting membrane potential of -70 mV, the electrical and concentration gradient for Na+ favors flux into the cell

With an extracellular concentration of 5mmol/L and the intracellular concentration of 150mmol/L, the equilibrium potential for  K+ in a typical neuron is -90mV

At the resting membrane potential of -70 mV, the electrical gradient K+ favors flux into the cell, while the concentraton gradient favors flux out of the cell
