Answer:

At the same time sodium channels open, gK + and outward directed K + currents fall as potassium channels close. These two conductance changes move the membrane potential away from E K (which is negative) and closer toward the equilibrium potential for sodium (E Na), which is positive.

Step-by-step explanation:

Hope this helps you
