Na+/K+-ATPase is a key enzyme in cells, responsible for pumping Na+ out and K+ in, using ATP. It maintains the electrochemical gradient essential for nerve impulses, muscle contraction, and cell volume regulation. The enzyme is also involved in cellular metabolism, secondary active transport for nutrient uptake, osmotic balance, and signaling pathways affecting neurological functions.
