1. Organic Molecules What do you think are the most common elements in the human body? (Hint: look at p. 113 in your pride book to help)

2. Role of Carbon 4 valence electrons free Can covalently bond with up to 4 other atoms

3. Polymer A large molecule formed when many smaller ones (monomers) bond together

4. Label each tab and put your name on it.

5. Number off 1-4  1’s carbohydrates  2’s lipids  3’s proteins  4’s nucleic acids For your molecule find:  3 Functions  1 Example

6. Carbohydrates Functions main source of energy Structural support in plants and fungi Ex:

7. Lipids Store energy (fats & oils) Important part of cell membranes (phospholipid/cholestrol) Waterproof coverings (waxes)

8. Proteins Control rate of reactions and cell processes as enzymes Found in bones and muscles Help to fight disease (antibodies)

9. Nucleic Acids Stores (DNA) and transmits (RNA) genetic information to build proteins

10. Lipids

11. Nucleotides

12. Carbohydrates Functions main source of energy Structural support in plants and fungi

13. Proteins

14. Enzymes  biological catalysts  Speeds up reactions  Without them reactions would occur too slow for life  Lower the activation energy

15. Enzymes Enzymes provide a site where substrates can be brought together = Active Site  The fit is like a lock and key

16. Enzyme Regulation Work best at a particular pH  Digestion enzyme Affected by changes in temperature  Denaturization Concentration
