Structure and Function of Plasma Membranes
Components and Structure
The plasma membrane determines what goes in and out of the cell, gives the cell flexibility, and transmits signals.
Fluid Mosaic Model
The fluid mosaic model describes the plasma membrane structure as a mosaic of phospholipids, cholesterol, proteins, and carbohydrates.
The mosaic nature of the membrane, its phospholipid chemistry, and the presence of cholesterol contribute to membrane fluidity.
