Answer: option D

The sodium potassium ion exchange move sodium and potassium in opposite direction in electrochemical gradients.

Explanation:

The sodium potassium pump is found in many animals plasma membranes and its moves the sodium and potassium ion in opposite direction across the plasma membrane with the hydrolysis of ATP(adenosine triphosphate) to supply the needed energy. It is an active transport process.
