2. In a catalyzed reaction, a reactant is often called a(n) substrate.

3. An enzyme is specific because the shape of its active site matches only particular reactants.

4. An enzyme speeds up reactions by lowering the activation energy

5. The induced fit between an active site and its substrate often strains bonds and helps the reaction proceed.

6. A(n) coenzyme, which is often a vitamin, binds to an enzyme and plays a role in catalysis.
