Question
The sodium-potassium pump facilitates to maintain the electrolyte gradient of a cell with the help of ATP. Which of the following best explains this type of transport?
- Active transport
- Passive transport
- Facilitated diffusion
- Simple diffusion
The correct answer is: Active transport
The sodium-potassium pump carries out a form of active transport—that is, its pumping of ions against their gradients requires the addition of energy from an outside source.
