Question

An enzyme is considered a(n) because it speeds up a chemical reaction without being used up. 2. in a catalyzed reaction, a reactant is often called a(n) . 3. an enzyme is specific because the shape of its matches only particular reactants. 4. an enzyme speeds up reactions by lowering the . 5. the between an active site and its substrate often strains bonds and helps the reaction proceed. 6. a(n) , which is often a vitamin, binds to an enzyme and plays a role in catalysis. 7. high temperatures or changes in ph can an enzyme, causing it to lose its shape and biological activity.

Answer 1

1 is catalyst
2 is substrate
3 is active site
4 is activation energy
5 is ions
6 is ion
7 is denature

Answer 2

Answer: 1. The answer is a catalyst

2. The reactant is called a substrate.

3. It is because of the active site.

4. It lowers the reactions activation energy.

5. The ions

6. The answer is ions

7. The answer is a denature
