The sodium potassium pump requires ATP - i.e. it is involved in active transport, not facilitated transport.
Secondary active transport aka facilitated diffusion [depending on your teacher].

Active transport
Yes, the sodium-potassium pump is a type of carrier protein that helps transport sodium and potassium ions across the cell membrane.
sodium-potassium pump.
The sodium-potassium pump uses one molecule of ATP to transport three sodium ions out of the cell and two potassium ions into the cell.
B: A Sodium-potassium pump
transport across the membrane
The sodium-potassium pump uses ATP as a cofactor to transport sodium out of the cell and potassium into the cell against their concentration gradients. This process is crucial for maintaining the cell's membrane potential and regulating cellular volume.
During active transport in the sodium-potassium pump, three sodium ions are pumped out of the cell while two potassium ions are pumped into the cell against their concentration gradients, using energy from ATP.
The sodium-potassium pump is an active transport pump that helps move sodium ions out of the cell and potassium ions into the cell against their concentration gradients. This process requires energy in the form of ATP to pump the ions across the cell membrane. The sodium-potassium pump is essential for maintaining the cell's resting membrane potential and is involved in regulating cell volume and transmitting nerve impulses.
