Na+/K+Na raised to the positive power / K raised to the positive power -ATPase pumps three Na+Na raised to the positive power ions out of the cell and two K+K raised to the positive power ions into the cell per molecule hydrolyzed. This maintains low intracellular Na+Na raised to the positive power and high intracellular K+K raised to the positive power : Ca 2+raised to the 2 plus power

: The sodium-calcium exchanger (NCX) uses the incoming Na+Na raised to the positive power role of active transport

) to pump ions, nutrients, and waste products across biological membranes against their concentration or electrochemical gradients. Without this specialized mechanism, cells could not generate electrical impulses, absorb essential nutrients, or eliminate toxic waste products. 1. Establishing and Maintaining Concentration Gradients Na+/K+Na raised to the positive power / K

Foreman stood atop the central Pump platform, barking orders. He was a specialized worker whose sole job was to manage the currency of the city: ATP (Adenosine Triphosphate). A massive battery was wheeled into the center of the Pump

A massive battery was wheeled into the center of the Pump. With a sickening crunch, the energy was released— hydrolysis . The ATP snapped apart, releasing a jolt of power that caused the Pump to shudder and change shape.
