Answer:
Within an enzyme, there are defined structures called active sites. The active site of an enzyme is specific to the substrate, or chemical that the protein reacts with. The substrate binds to the enzyme at its active site, the chemical reaction takes place, and the products are released.
When enzymes are changed, it is at the active site. Usually, an enzyme and its substrate meet at its active site, and they fit together perfectly, in a jigsaw puzzle format or a lock and key format. However, sometimes the substrate and the enzyme do not fit perfectly, but the enzyme still accepts the substrate at its active site in what is called the induced fit model. If the enzyme accepts the substrate, the reaction takes place and the active site changes to fit the substrate.
If its tertiary structure is changed too much, however, the active site of an enzyme will not accept the substrate, and the chemical reaction will not take place.
