Description

There may be a dozen different types of materials passing through the membrane of a cell at any one time. The job of the membrane is to regulate this movement in order to maintain the proper balance of ions, water, oxygen, carbon dioxide, nutrients, and other molecules. This interactive feature illustrates the movement of some of these materials and describes the structures that make it possible.
