Transport through cell membranes

Transport through cell membranes. Transport through cell membranes. The phospholipid bilayer is a good barrier around cells, especially to water soluble molecules. However, for the cell to survive some materials need to be able to enter and leave the cell. There are 4 basic mechanisms:
