Facilitated Diffusion - Definition, Examples & Quiz

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. Being passive, facilitated transport does not directly require chemical energy from ATP hydrolysis in the transport step itself… WebMain difference: In facilitated diffusion, the solute moves down the concentration gradient, from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. … WebThe facilitated diffusion does not need energy during transportation of molecules through the cell membrane because the molecules are transported from high concentration … jewellery furniture for sale
