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… WitrynaThe movement of substances in and out of the cell without any energy input is known as passive transport. Generally, this involves the movement of molecules/ions from a region of high concentration (e.g. high concentration of molecules or ions in the extracellular environment) to an area of low molecule/ion concentration (e.g. inside … recreation warehouse naples flWitrynaThus, transport by carriers can be either active or passive, whereas transport by channel proteins is always passive.
