17 Questions

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

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

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

4. Occurs when the control changes the enzymes shape

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

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

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

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

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

10. Bond to another spot causing the shape to change

11. Blocks the active site

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

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

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

15. Name the four enzyme controls

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

17. The biological molecule that the enzymes will work on
