What is the Origin of Na+/K+-ATPase Pump?

Discovered in 1957, the term is descriptive, combining the two primary ions transported (Sodium, $text{Na}^{+}$; Potassium, $text{K}^{+}$) with the energy source utilized (ATPase, an enzyme that hydrolyzes Adenosine Triphosphate). Its discovery established the fundamental principle of active transport against a concentration gradient, which is a cornerstone of human physiology.

What is the Mechanism of Na+/K+-ATPase Pump?

For every molecule of ATP hydrolyzed for energy, the pump actively transports three sodium ions ($text{Na}^{+}$) out of the cell and simultaneously imports two potassium ions ($text{K}^{+}$) into the cell, both moving against their respective concentration gradients. This unequal exchange of positive charges establishes a net negative charge inside the cell, creating the negative resting membrane potential. This sustained gradient is critical for the excitability of nerve and muscle cells and for driving secondary active transport mechanisms.

Meaning

The $text{Na}^{+}/text{K}^{+}$-$text{ATPase}$ Pump is an electrogenic transmembrane protein enzyme, commonly known as the sodium-potassium pump, that is ubiquitously expressed in the plasma membrane of nearly all animal cells. This vital enzyme functions to actively transport ions across the cell membrane, which is essential for maintaining the necessary electrochemical gradients. Its proper function is crucial for cellular volume regulation, nerve signaling, and the contractile function of muscle tissue, including the heart.
