The sodium-potassium pump pumps sodium ions ____ and potassium ions ____.

Question

Quizplus · Accepted Answer

The sodium-potassium pump is a type of membrane transport protein that pumps three sodium ions out of the cell for every two potassium ions it pumps in. This creates an electrochemical gradient that is important for many cellular processes such as muscle contraction and nerve impulse transmission. Therefore, the correct choice is out of the cell for sodium ions and into the cell for potassium ions, which is only represented by option D.

The Sodium-Potassium Pump Pumps Sodium Ions ____ and Potassium Ions
