Across
- 4. The minimum exertion of power needed for a chemical reaction to take place
- 6. The chemical process where organisms use food and water to grow, heal and to make energy
- 7. Nutrients your body needs from food in small amounts for growth and maintaining a good health; also acts as coenzymes in the regulation of metabolic processes
- 10. An organ located at the base of the neck that releases hormones to control metabolism as well as growth and development
- 12. A molecule that binds to the active site and prevents the enzyme from binding to to the substrate. A reaction cannot occur because the active site is blocked
- 14. A concept where the enzyme and the substrate fit together perfectly; the correct size and shape of the substrate would fit into the active site of the enzyme
- 15. The main hormone produced by the thyroid gland that increases metabolic rate; also regulates growth and development
Down
- 1. Altering the shape of a protein through extreme heat, pH changes or heavy metals that causes a protein to lose its function
- 2. A molecule that binds to an enzyme that is not the active site and changes the active site so the enzyme cannot bind with the substrate
- 3. Proteins that act as a catalyst in living organism to speed up the rate of chemical reactions without being used up
- 5. Small molecules that enhances the action of a protein that acts as catalyst to speed up chemical reactions
- 8. A substance acted upon by an enzyme
- 9. The area of an enzyme where the substrates bind with the enzyme and undergoes a chemical reaction
- 11. Protein portion of the organic molecule that speeds up reaction
- 13. A concept where enzymes slightly alter the shape of their active site to fit the substrates better
