Verified step by step guidance

Understand the concept of active transport: Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, using energy in the form of ATP.

Learn about the sodium-potassium pump: The sodium-potassium pump is a type of active transport mechanism that moves sodium ions out of the cell and potassium ions into the cell against their concentration gradients.

Differentiate between symporters and antiporters: Symporters transport two different molecules in the same direction across the membrane, while antiporters transport two different molecules in opposite directions.

Identify the type of transport used by the sodium-potassium pump: The sodium-potassium pump is an example of an antiporter because it moves sodium ions out of the cell and potassium ions into the cell in opposite directions.

Conclude the type of transport: Since the sodium-potassium pump uses energy to move ions against their concentration gradients and functions as an antiporter, it is classified as active transport through an antiporter.
