Question

multiple - choice question charged ions are traveling through a cell membrane with the concentration gradient. which process is represented here? active transport facilitated diffusion simple diffusion

Explanation:

Charged ions moving through a cell - membrane with the concentration gradient is facilitated diffusion. Active transport moves substances against the concentration gradient. Simple diffusion is for non - charged small molecules moving down the concentration gradient without a carrier. Ions need a transport protein to cross the membrane down the concentration gradient, which is facilitated diffusion.

Answer:

facilitated diffusion
