Select the descriptions that apply to the sodium-potassium pump: The pump helps to maintain the concentration of sodium and potassium ions in living cells. Sodium ions and potassium ions move into and out of the plasma membrane by active transport. The concentration gradient of the ions determines the direction of movement through the pump. The pump is an active mechanism for transporting ions through the plasma membrane.

The sodium-potassium pump helps establish an electrochemical gradient across the membrane. It concentrates sodium on the outside of the membrane. It uses a carrier protein and chemical energy. It is present in the plasma membrane. All of these are correct.
The sodium-potassium pump moves Multiple Choice sodium ions out of the cell and potassium ions into the cell. sodium ions into the cell and potassium ions out of the cell. sodium and potassium ions into the cell. sodium and potassium ions out of the cell. sodium and potassium ions in both directions across the cell membrane.
