Selective Permeability The plasma membrane is composed of a PHOSPHOLIPID bilayer, in which TWO layers of phospholipids are arranged tail-to-tail (which allows it to exist in a watery environment) Each phospholipid consists of a “head” with TWO “tails” The “head” is a PHOSPHATE which is ...
plasma membrane- a thin membrane (a double layer of lipids) enclosing the cytoplasm of a cell; proteins in the membrane control passage of ions (like sodium or potassium or calcium) in and out of the cell; "all cells have a cell membrane" ...

This chapter discusses the importance of plasma membrane proteins in carrying out numerous cellular functions at the interface between the internal and external environments. The plasma membrane is actively involved in the uptake by endocytosis of a variety of materials from the surrounding medium. The...
