There are several different types of this easy movement of molecules. You may also see proteins in the cell membrane that act as channels to help the movement along. Of course there is an in-between transport process where very small molecules are able to cross a semi-permeable membrane. Proteins are used to help move molecules more quickly. Since the cell membrane will not allow glucose to cross by diffusion‚ helpers are needed. The cell might notice outside fluids rushing by with
