Question

What is the diferent between diffusion and facilitaed diffusion

Answer 1

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.

Answer 2

Simple diffusion is passive but facilitated diffusion is an active process

Step-by-step explanation:

In facilitated diffusion, molecules just move by the help of a protein in the membrane. Simple diffusion is passive while facilitated diffusion is an active process that utilizes energy. Simple diffusion needs molecules to move within special doorways in the cell membrane.
