Another Cellualar Switch....

a: Cell receptor ~
b: kind of switch

What: "Each cellular receptor is like a kind of switch connected to a lock-and-key mechanism, similar to the ignition system for a car. Only the binding of a specific chemical to the receptor will trigger the molecular switch, just as a car will start only if the correct key is inserted into its ignition."
