3/25 facilitated diffusion passive transport active transport
Facilitated diffusion is a type of passive transport. In passive transport, substances move across the cell membrane from an area of higher concentration to an area of lower concentration without the use of energy. Active transport, on the other hand, requires energy as substances move against the concentration gradient (from lower to higher concentration). The image shows movement along the concentration gradient (as indicated by the arrows) with the help of transport proteins (the cylindrical structures), which is characteristic of facilitated diffusion (a form of passive transport).
