Components of Plasma Membranes
The plasma membrane protects the cell from its external environment, mediates cellular transport, and transmits cellular signals.
Fluid Mosaic Model
The fluid mosaic model describes the plasma membrane structure as a mosaic of phospholipids, cholesterol, proteins, and carbohydrates.
Membrane Fluidity
The mosaic nature of the membrane, its phospholipid chemistry, and the presence of cholesterol contribute to membrane fluidity.
