The answer is through facilitated diffusion. It is then called as the transport of substances in a biological membrane from a higher concentration to a lower concentration area though carrier proteins. Hope this is the right answer and would be of help.
<span>Some particles or molecules are too large to be actively
transported by carrier proteins so they use active transport processes to move these macro-molecules into or
out of the cell. In addition, active transport processes has two types of vesicle transport namely endocytosis and exocytosis,
They both require energy to facilitate the process. </span>
