Question

membrane proteins
what type of membrane protein is the na⁺/k⁺ atpase pump considered?
enzyme
transmembrane
peripheral
transatlantic

Explanation:

The Na⁺/K⁺ ATPase pump spans the cell - membrane, which is characteristic of transmembrane proteins. It actively transports sodium and potassium ions across the membrane and also has enzymatic activity (hydrolyzes ATP), but its structural nature as a membrane - spanning protein is key. Peripheral proteins are loosely associated with the membrane, and "Transatlantic" is not relevant here.

Answer:

B. Transmembrane
