a type of passive transport (spontaneous), therefore, it is a net movement of molecules in and out of the cell across the cell membrane along a concentration gradient (higher concentration to lower concentration). |
|
facilitated diffusion |
when molecules move ( diffuse) via special transport proteins found within the cell membrane. |
