Illustration of permease membrane transport proteins (brown) moving molecules (green) across a cell's plasma membrane (yellow). This class of transmembrane proteins facilitates the movement of specific molecules across the cell membrane. This is a form of passive transport as molecules are only able to move from an area of high concentration to an area of low concentration. | |
