Short Definition For Facilitated Diffusion
Facilitated diffusion occurs in the cell body.
Short definition for facilitated diffusion. Facilitated diffusion is the transport of substances across a biological membrane from an area of higher concentration to an area of lower concentration with the help of a transport molecule. It is the process of transporting particles into and out of a cell membrane. It is a selective process i e the membrane allows only selective molecules and ions to pass through it. It however prevents other molecules from passing through the membrane.
Facilitated diffusion is the process of biological transport in which specific structural components of biological membranes interact with particular solutes or classes of solutes markedly increasing the rates at which they can cross the membrane. Energy is not required because the particles move along the concentration. Facilitated diffusion also known as facilitated transport or passive mediated transport is the process of spontaneous passive transport as opposed to active transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. Facilitated diffusion is the passive movement of molecules along the concentration gradient.
