Definition Of Facilitated Diffusion In Biology

Facilitated diffusion does not directly involve high energy molecules like adenosine triphosphate atp or.

Definition of facilitated diffusion in biology. However there is a phenomenon known as facilitated diffusion which occurs at the cellular level. 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 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. Since the movement of substances is from greater to lesser concentrations chemical energy is neither used nor required.
