Question : Differentiate between Simple diffusion and facilitated diff

1.	Question : Differentiate between Simple diffusion and facilitated diffusion
Answer» Solution :Transport of metabolites across the membrane along the concentration gradient and without the use of a carrier molecule is called simple diffusion. It is a SLOW process. On the contrary, facilitated diffusion is a more rapid FORM of diffusion, in which the MOLECULES MOVE through channels in the membrane. In facilitated diffusion a carrier (PROTEIN) is required for transport acrossthe membrane.
