With the aid of a transport molecule, chemicals can be transported across a biological membrane from a region of higher concentration to an area of lower concentration.
The process of spontaneous passive transport of molecules or ions across a biological membrane by certain transmembrane integral proteins is known as facilitated diffusion. It is sometimes referred to as facilitated transport or passive-mediated transport.
The passage of certain chemicals through protein channels to traverse cell membranes. It is a sort of passive transport, thus it is not quite diffusion. proteins for transport. proteins that assist in moving materials across cell membranes and throughout the body.
Facilitated diffusion is demonstrated by the movement of amino acids and glucose into cells from the circulation. These molecules are ingested by active transport in the small intestine and subsequently released into the circulation.
Thus, the chemicals can be transported across a biological membrane from a region of higher concentration to an area of lower concentration.
