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 plasma membrane (PM) surrounds all living cells and is the border checkpoint regulating transport and maintaining cytoplasmic homeostasis. The PM is composed of a phospholipid bilayer containing proteins that are important for transport across this barrier. These transport proteins operate with three...

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...

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...
