Final answer:
The sodium-potassium pump, also known as the Na+-K+ pump, works to maintain equilibrium and ion gradients in living cells. It moves 3 Na+ ions out of the cell for every 2 K+ ions it pumps into the cell. This process is crucial for establishing and maintaining the resting membrane potential of cells.
Step-by-step explanation:
The sodium-potassium pump, also known as the Na+-K+ pump, is responsible for maintaining equilibrium and ion gradients in living cells. It moves 3 Na+ ions out of the cell for every 2 K+ ions it pumps into the cell. This process requires the hydrolysis of ATP to provide the necessary energy.
By actively transporting ions against their concentration gradients, the Na+-K+ pump helps to establish and maintain the resting membrane potential of cells. This is crucial for various cellular functions, including nerve impulse transmission and muscle contraction.
Overall, the Na+-K+ pump plays a vital role in maintaining ion balance and equilibrium within cells, ensuring proper cellular function.
