WebDescription: It is also called plasma membrane or cell membrane. The plasma membrane is a semi-permeable membrane that separates the inside of a cell from the outside. Structure and Composition: In eukaryotic cells, the plasma membrane consists of proteins, carbohydrates and two layers of phospholipids (i.e. lipid with a phosphate group). WebMost higher eukaryotic plasma membrane proteins are synthesized on a. free ribosomes and inserted after translation into the plasma membrane. b. rough ER ribosomes and carried to the plasma membrane by vesicles that pinch off from the Golgi apparatus.
