A sodium-potassium pump is an example of ______.
- Primary active transport method
- Secondary active transport method
- Primary passive transport system
- Secondary passive transport system
Hint:
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.
