Examples of Facilitated Diffusion?

Answer

Facilitated diffusion is the movement of particular molecules across a cell membrane through protein channels. It is a process of passive transport, made possible by integral proteins. It is the spontaneous passage of ions or molecules across a biological membrane via specific trans-membrane integral proteins.

Facilitated diffusion refers to a biological process of passive transport that allows substances to cross membranes facilitated by integral proteins. The process can either occur across biological membranes or via aqueous compartments of an organism.
Facilitated diffusion is the transport of substances across a membrane by a trans-membrane protein molecule.
In the process known as facilitated diffusion, a special carrier protein with a central channel acts as a selective corridor which helps molecules move across the membrane. The facilitator is an integral membrane protein that spans the width of the membrane. The force that drives the molecule from one side of the membrane to the other is the force of diffusion.
Facilitated Diffusion is a transportation process in which many substances cross a membrane with transport proteins. The proteins play an integral part in the transportation process. The proteins bind to the molecules.
