If the concentration of K⁺ is higher outside a plant cell than inside, K⁺ will enter the cell by: A)facilitated diffusion through channel proteins. B)simple diffusion through channel proteins. C)facilitated diffusion via carrier proteins. D)active transport through channel proteins. E)active transport via carrier proteins.

Question

Quizplus · Accepted Answer

Facilitated diffusion through channel proteins allows ions like K+ to move down their concentration gradient without the use of energy, which is the case when K+ concentration is higher outside the cell.
