Which statement is accurate concerning simple diffusion and facilitated diffusion? In facilitated diffusion, molecules only move with the aid of a protein in the membrane. In simple diffusion, molecules move down the concentration gradient but in facilitated diffusion molecules move up the concentration gradient. Simple diffusion is passive but facilitated diffusion is an active process that uses energy. Simple diffusion requires molecules to move through special doorways in the cell membrane.
