Question

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

Explanation:

The Na⁺/K⁺ ATPase pump spans the cell - membrane. Transmembrane proteins are those that cross the entire lipid - bilayer of the membrane. Peripheral proteins are associated with the membrane surface. While the Na⁺/K⁺ ATPase has enzymatic activity (it is an ATPase), the question asks about its membrane - protein type. "Transatlantic" is not relevant to membrane - protein classification.

Answer:

A. Transmembrane
