Answer :
Facilitated diffusion is a sort of passive transport that speeds up the flow of materials by using specific proteins.
Passive transport is a subset of facilitated diffusion. Because the solution travels down the concentration gradient, assisted diffusion is still passive transport even when it incorporates transport proteins. With the aid of a transport molecule, chemicals may be transported across a biological membrane from a region of greater concentration to an area of lower concentration. Chemical energy isn't directly needed since substances flow in the direction of their concentration gradient. Transport of glucose and amino acids, gases, and ions are a few biological activities that use assisted diffusion. Because it regulates what enters and leaves the cell, facilitated diffusion is important. The cellular component that controls the selective transport of chemicals is the plasma membrane.
