Whats the difference between simple and facilitated membrane

What’s the difference between simple and facilitated membrane transport?

Answer:

Simple diffusion

Facilitated diffusion

Molecules move from a region of high concentration to low concentration across the membrane. It doesn’t need any transporter proteins

Molecules move from a region of high concentration to low concentration across the membrane. But it needs transporter proteins.

Small molecules will pass through simple diffusion

Large molecules will pass through facilitated diffusion

Passive transport
