This picture is a representation of what type of transport?

• Osmosis because it is diffusing through a protein from an area of high concentration to low concentration.

• Facilitated diffusion because it is diffusing through a protein from an area of high concentration to low concentration.

• Facilitated diffusion because it is diffusing through a protein from an area of low concentration to high concentration.

• Simple diffusion because it is diffusing through a protein from an area of high concentration to low concentration.
