Uphill transport

Vedclass · Answer

(B) The correct answer is $B$. Facilitated transport (or facilitated diffusion) is the spontaneous movement of molecules or ions across a biological membrane through specific transmembrane integral proteins. It is a passive process,meaning it does not require energy $(ATP)$. Facilitated diffusion is mediated by protein channels and carrier proteins. Most transport proteins involved in this process are highly selective and only transport specific molecules. Since it is a passive process,molecules move down their concentration gradient,which is known as 'downhill transport'. 'Uphill transport' refers to active transport,where molecules move against their concentration gradient,requiring energy. Therefore,uphill transport is not a characteristic of facilitated transport.
