Which is TRUE about the Na⁺, K⁺ ATPase pump in neurons? A) It generates a small electrical potential such that the inside is made negative with respect to the outside. B) It maintains a concentration gradient for K⁺ such that diffusion forces favor movement of K⁺ into the cell. C) It maintains an electrical gradient at the equilibrium potential of K⁺. D) It transports equal numbers of sodium and potassium ions with each pump cycle. E) It pumps 3 Na⁺ ions into the cell for every 2 K⁺ ions it pumps out.

Question

Quizplus · Accepted Answer

The Na⁺, K⁺ ATPase pump generates a small electrical potential by pumping 3 Na⁺ ions out of the cell and 2 K⁺ ions into the cell, making the inside of the cell more negative relative to the outside.
