Work Step by Step
Functions of proteins include:
- Channel proteins are involved in passing molecules through the membrane.
- Carrier proteins are also involved in passing molecules through the membrane.
- Cell recognition proteins are glycoproteins (Fig. 5.2c). Among other functions, these proteins help the body recognize when it is being invaded by pathogens, so that an immune response can occur.
- Receptor proteins have a shape that allows only a specific molecule to bind to it
- Enzymatic proteins Some plasma membrane proteins are enzymes that carry out metabolic reactions directly
- Junction proteins Proteins are involved in forming various types of junctions between animal cells
