Na k atpase pump

Schematic biomedical diagram of the sodium-potassium ATPase as a large asymmetric transmembrane pump spanning a lipid bilayer. The protein has a bulky globular cytoplasmic ATPase domain, several rounded membrane-spanning lobes, and a central channel-like ion transport core with distinct inward- and outward-facing aspects. It is colored in blue, teal, blue-green, or blue-purple, sometimes with gold accents, and may show an ATP-binding site plus implied sodium and potassium exchange features such as directional transport, binding pockets, or three sodium-binding sites on one side and two potassium-binding sites on the other. Rendered as a clean stylized molecular transporter icon or clipart-style scientific illustration.
