The Na/K-ATPase pump or sodium-potassium pump will take out sodium ion from cells and take in potassium ion as the exchange. This is why in normal condition the concentration of sodium ion is higher outside cells but the concentration of potassium ion is higher inside cells. If the pump activity is increased, this will also increase the concentration gaps. So
1. sodium ion inside cells will be lower
2. potassium ion inside cell will be higher
