How do electrolytes move into and out of cells?

Question

Quizplus · Accepted Answer

Electrolytes cannot move across the cell membrane by simple diffusion or facilitated diffusion as they are charged ions. They require active transport mechanisms such as ion pumps or carriers to move them against the concentration gradient. Therefore, the best choice is C, active transport. Exocytosis is not an appropriate answer as it is a process by which cells secrete substances out of the cell, and it does not apply to the movement of electrolytes into or out of cells.
