Facilitated Diffusion Biology Discussion. 10242015 Diffusion is an effective means of transport of substances helps in the translocation of food material. Essentially just tunnels through the membrane.
Facilitated diffusion is the process of transporting particles into and out of a cell membrane. Facilitated diffusion takes place due to a difference in concentration on both sides of the membrane in the direction of the lowest concentration and does not require energy. Facilitated diffusion is believed to result from the interaction of solute with specific membrane molecules presumably proteins thereby forming a carrier-solute complex.

A solid has its molecules tightly packed. A solid has its molecules tightly packed. Some molecules such as carbon dioxide and oxygen can diffuse across the plasma membrane directly but others need help to cross its hydrophobic core. In a solid substance however facilitated diffusion definition does not occur in them.
