17 Questions

1. Make enzymes work harder and faster. can help the enzyme bind to the substrate.

2. Causes shape changes. can mess up the process and the enzymes won't work

3. Specially shaped area of the enzyme that fits around the substrate (keyhole of the lock)

4. Biological substance (proteins) that act as Catalysts and help complex reactions occur everywhere in life.

5. A substance that increases the rate of a chemical reaction by reducing the amount of energy needed to start that reaction

6. The amount of energy needed to start a chemical reaction

7. Bond to another spot causing the shape to change

8. When the enzyme lets go, it returns to normal, ready to do another reaction

9. When shape changes, the enzyme will not work the same way. Name two nasty examples of an inhibitor.

10. Occurs when the control changes the enzymes shape

11. Can also change the shape of the protein. the proteins denature if too acid or too basic

12. Either slow down or stop the activity of an enzyme.

13. When the substrate is changed-can be broken down or combined with another molecule to make something new

14. Name the four steps in the process of an enzyme working

15. The biological molecule that the enzymes will work on

16. Name the four enzyme controls
