The Na⁺/K⁺ pump is crucial for resting membrane potential (approximately -70 mV). By constantly pumping out Na⁺ and bringing in K⁺, the pump ensures neurons are ready to fire an action potential. After depolarization, active transport helps restore ion distribution, allowing the nerve to repolarize.
A common misconception is that any transport involving a protein is "active." This is false. active transport in humans
