Description: Facilitated diffusion is a carrier-mediated transpo. ATP is not consumed in this transpo. A conformational change in the carrier molecule causes the substance to be transpoed to the other side of the membrane. Some models hypothesised for the carrier proteins ~ flip-flop model, ferryboat model. Saturability, Specificity and inhibition are the characteristics of the Facilitated diffusion
