The plasma membrane is a semipermeable barrier that encloses intracellular components from the extracellular environment. In addition to the phospholipid bilayer, proteins are estimated to constitute as much as 50% of plasma membrane biomass. The cell surface proteome can be divided into integral membra...

The generally accepted picture of the plasma membrane as a lipid bilayer continuum containing integral proteins is illustrated. The physico-chemical properties of the lipid bilayer in model systems such as black lipid membranes (BLM) and lipid bilavers from hydrophobic apposition of monolayers are ...
Structure of the Plasma Membrane The phospholipid bilayer The plasma membrane is composed of phospholipid bilayer – two layers of phospholipids are arranged to allow the membrane to exist in a watery environment. The phospholipid bilayer has polar heads facing outside and nonpolar tails facing inside...

But HOW? Water is small but polar, so it can’t simply diffuse through the phospholipid bilayer… HOW DO THINGS GET IN AND OUT OF A CELL? Several different processes are involved in moving materials across the cell membrane…. PASSIVE TRANSPORT: The movement of a substance across a cell me...
Thecell membraneis an extremely pliable structure composed primarily of back-to-back phospholipids (a “bilayer”). Cholesterol is also present, which contributes to the fluidity of the membrane, and there are various proteins embedded within the membrane that have a variety of functions. A single...
