  2. Secondary active transport method
  3. Primary passive transport system

hintHint:

The sodium-potassium pump is a primary active transport method.

The correct answer is: Primary active transport method


    • Sodium-potassium pump helps to maintain a high concentration of potassium in and sodium out of the cell.
    • It uses the energy directly from the breakdown of ATP.
    • This is called primary active transport which allows the secondary active transport to take place.
