Where does the substrate connect to the enzyme?

The molecules that an enzyme works with are called substrates. The substrates bind to a region on the enzyme called the active site. There are two theories explaining the enzyme-substrate interaction. In the lock-and-key model, the active site of an enzyme is precisely shaped to hold specific substrates.
