Physiology Quiz -
The Na⁺/K⁺ ATPase - Part 2

The Na⁺/K⁺ ATPase (or simply Na⁺ pump) is a ubiquitous membrane transport protein found in all body cell types. Test your basic knowledge of the Na⁺/K⁺ ATPase by taking this simple quiz.

(1) The Na⁺/K⁺ ATPase is an active transporter.

	True
	False

(2) The Na⁺/K⁺ ATPase is a primary active transporter.

	True
	False

(3) The Na⁺/K⁺ ATPase is a secondary active transporter.

	True
	False

(4) The Na⁺/K⁺/ATPase is an electrogenic transport protein.

	True
	False

(5) For every ATP molecule hydrolyzed by the Na⁺/K⁺ ATPase (also referred to as the Na⁺ pump):

	(A) 2 Na⁺ ions are transported into the cell and 3 K⁺ ions are transported out of the cell.
	(B) 2 Na⁺ ions are transported out of the cell and 3 K⁺ ions are transported into the cell.
	(C) 3 Na⁺ ions are transported into the cell and 2 K⁺ ions are transported out of the cell.
	(D) 3 Na⁺ ions are transported out of the cell and 2 K⁺ ions are transported into the cell.
	(E) None of the above is correct.

(6) The Na⁺/K⁺ ATPase is a housekeeping protein that is found in all body cell types.

	True
	False
