Structure of the plasma membrane (article) Khan Academy

網頁Structure and Composition of the Cell Membrane. The cell membrane is an extremely pliable structure composed primarily of two layers of phospholipids (a “bilayer”). Cholesterol and various proteins are also embedded within the membrane giving the membrane a variety of functions described below. 網頁Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment.This double layer consists largely of specialized lipids … 網頁1) Membrane proteins perform a variety of functions and vary in shape. 2) Some proteins function as receptors on the cell surface, starting signal transduction. 3) Other proteins … echte island pullover
