1. BELLWORK: WRITE DOWN ONLY WHAT THE QUESTION IS ASKING AND YOUR ANSWER…

2. Standard 9A – Compare the structures and functions of different types of biomolecules. Essential Question What part does basic chemistry play in the structure biomolecules?

5. Cornell Note Examples

6. Intro to Biochemistry (pg. 24) *THE CHEMISTRY OF LIFE…

7. 1. Elements we need to recognize: C = Carbon H = Hydrogen O = Oxygen N = Nitrogen P = Phosphorus Molecule: two or more atoms bonded together Element: matter made of only one type of atom

8. Bonds, bonds, bonds!  Molecules are atoms bonded together.  The bond stores energy.  When that bond is broken, energy is released.  More bonds = More energy!!

9. How do bonds form and break?

10. 2. Chemical Reactions Chemical reaction = the process by which atoms bond together or break apart. A chemical bond occurs when two or more elements react together to form a chemical compound (molecule). The compound is unique from its parent atoms.

11. Chemical equation: How scientists describe a chemical reaction. Reactants : what goes IN to the chemical reaction, left side of arrow Products : what is produced from the reaction, right side of arrow ( Reactants ) ( Products ) 2Na + Cl 2  2NaCl

12. There are several important types of reactions that occur everyday Photosynthesis Cellular Respiration

13. There are several important types of reactions that occur everyday

14. Cooking Batteries

15. There are several important types of reactions that occur everyday Detergents

16. 3.Macromolecules A. Macromolecules = large molecules made from smaller molecules. B. Polymer (many parts) macromolecule made up of many smaller, repeating molecules. C. Monomer (one part) is a single unit which is bonded together to make polymers.

42. There are two types of reactions important to making monomers and polymers

43. 1. Dehydration synthesis = polymers are formed by removing water.

44. 2. Hydrolysis = breaking down polymers into monomers by the addition of H 2 O. Hydro=water Lysis=cut

45. 4. Organic chemistry : the study of compounds that contain carbon atoms. (Life on earth is considered carbon based). Organic = contains carbon Inorganic = does NOT contain carbon

46. B. There are four types of organic compounds found in living things… 1. Carbohydrates 2. Lipids 3. Proteins 4. Nucleic Acids
