Answer
$\text{The facilitated diffusion can be done in 2 ways: }$
$\text{(i). through a channel protein and }$
$\text{(ii). using a protein carrier which is specific for a particular chemical }$
$\text{These 2 ways differ as the first method is carried out by selecting the particle size and charge (mostly ions) while the second method is carried out by binding the substrate which causes to change shape to transport protein. }$
