Quizplus · Accepted Answer

Potassium ion (K+) is higher in concentration inside the cell compared to outside. This is because the cell membrane contains potassium channels that allow potassium ions to move in and out of the cell. The sodium-potassium ATPase pump also helps to maintain a higher concentration of potassium inside the cell.
