Biologically Active Regulators
Lipid bilayer membranes surround cells and also organelles throughout eukaryotic cells. It would be a mistake, however, to think of membranes simply as structural partitions between cells and parts of cells. Rather, membranes are biologically active. They regulate transport of compounds, interact with other cells, and are involved in cell signaling. Models in this section will explore these various functions of membranes.
