Topic 1.3
Essential idea: The structure of biological membranes makes them fluid and dynamic.
The the figure below shows the structure of the plasma membrane including phospholipid bilayer, cholesterol, glycoproteins, and integral and peripheral proteins. The term plasma membrane, not the cell surface membrane, is used for the membrane surrounding the cytoplasm. Integral proteins are embedded in the phospholipid bilayer, whereas peripheral proteins are attached to a surface.
