Facilitated diffusion is a form of facilitated transport involving the passive movement of molecules along their concentration gradient, guided by the presence of another molecule – usually an integral membrane protein forming a pore or channel.
Biology definition: Facilitated diffusion is the passive movement of substances, such as biological molecules or ions, across a plasma membrane by means of a transport protein located in the plasma membrane.
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. [1]
Facilitated diffusion is the passive movement of molecules along the concentration gradient. 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 diffusion of solutes through transport proteins in the plasma membrane. Channel proteins, gated channel proteins, and carrier proteins are three types of transport proteins that are involved in facilitated diffusion.
By definition, facilitated diffusion is a type of passive transport which utilizes 'agents' known as channel proteins and carrier proteins to speed up the transport process. Explore the importance, experiments & examples of it.
Facilitated diffusion Definition. Facilitated diffusion is a passive transport process in which specific molecules move across a biological membrane with the aid of specialized transmembrane proteins, following their concentration gradient without the direct use of energy.
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.
Facilitated diffusion (also known as facilitated transport) is a form of passive transport across a biological membrane in which a transporter protein facilitates (or mediates or catalyzes) the movement of an otherwise membrane-impermeant molecule or ion across the plasma membrane down its concentration or electrochemical gradient.
Facilitated diffusion is a type of passive transport.
