Fluid Mosaic Model

Cell membrane made up of

phospholipids, cholesterol, and proteins

Cell membrane

protects the cell from outside environment

Phospholipids

polar phosphate group with 2 fatty acid chains that makes up most of membrane

Cholestoral

Inserts between phospholipids to provide stability and maintain fluidity of cell membrane

Proteins

carry out all the membrane processes; acts as receptors to signal the cell about outside environment and can help transport materials in and out the cell

Integral protein

Integrated in the cell membrane

Peripheral protein

Sits on the cell membrane or on another protein

Glycolipids

Plays a role in cell communication where sugars would attach to lipids

Glycoproteins

Plays a role in cell communication where sugars would attach to a protein

Fluid Mosaic Model

Pieces of the cell membrane can move around (fluidity)
