Answer

In the Lock and Key Model, the substrate and the enzyme's active site are exact matches for each other. Only one substrate is the key that matches the lock of the active site. Once the enzyme locates the molecule that fits, the chemical reaction begins. After the products are released, the enzyme searches for another molecule that is a match.
