Uphill transport

Vedclass · Answer

(B) Facilitated diffusion is a type of passive transport where molecules move across the membrane along the concentration gradient (from a region of higher concentration to a region of lower concentration). Since it follows the concentration gradient,it is a 'downhill' process and does not require metabolic energy $(ATP)$. It requires specific membrane proteins (carrier or channel proteins) to facilitate the movement of hydrophilic molecules. It is also highly selective in nature. Therefore,'Uphill transport' is the incorrect characteristic,as it describes active transport.
