Plasma Membrane Proteins

3 Types/Locations of Membrane Proteins Integral Proteins – firmly stuck inside the membrane Transmembrane Proteins – go from one side of the membrane to the other (a type of integral protein) Peripheral Proteins – attached only to outer surfaces of membrane (easier to remove)

Integral Proteins Peripheral Proteins Transmembrane Protein

What do Proteins do for the Cell Membrane? Help in cell-to-cell recognition Anchor the membrane to the cytoskeleton Help cell transport materials in/out of cell

Transport Proteins Transport Proteins – move materials in and out of cell through channels that open and close (this is how most ions pass through the membrane) Types of Transport Proteins: Channel Proteins = open pore for things to pass through Carrier Proteins = selectively bind to substance and then change shape to allow passage

Other Parts of the Plasma Membrane Cholesterol molecules – found inside the membrane to help keep the tails of the phospholipids from sticking together Carbohydrates – stick out from cell and help cells identify each other using chemical signals Cell Cell Membrane Carbohydrates

Carbohydrates on outside of cell membrane Cholesterol stuck inside the cell membrane
