The sodium-potassium pump uses active transport. This type of transport is necessary because it helps maintain the essential concentration gradients of sodium and potassium ions across the cell membrane, which are crucial for various cellular functions, including nerve impulse transmission, muscle contraction, and overall cellular homeostasis. Active transport requires energy (in the form of ATP) to move ions against their concentration gradients, ensuring that sodium is kept at a lower concentration inside the cell and potassium at a higher concentration, allowing the cell to function properly.
