1. BELL WORK (Buff Binder): On a SEPARATE, BLANK sheet of notebook paper (NOT in your journal!!)… List three similarities and three differences for carbohydrates & lipids. Think about shape, function, elements, etc.

2.  Open your journal to the next blank page and set up Cornell Notes.  Page: 23  Title: Proteins  Date: 9-29-14  Essential Question: What are the characteristics of a protein?

3. Structure discovery: For the next few minutes discuss the following questions at your table: How would you describe the structure (shape) of this biomolecule? What elements are present? How is it different from carbohydrates & lipids?

4. Structure : variety of different shapes contain Carbon, Hydrogen, Oxygen, and Nitrogen contain an “R” group

5. Structure: Monomer = amino acid There are 20 essential amino acids, with the same basic structure. The difference is in the “R” group. Amino acids form peptide bonds between them to create… Polymer = polypeptide

6. The “R” group is the amino acid’s “ID card” Each “R” group has a charge that will attract or repel other “R” groups This causes the polypeptide chain (protein) to fold and twist in very unique ways

7. Some examples of Polypeptide shapes….

8.  determine your traits ◦ Skin, bone, hair, ear wax color, and even body odor can all be attributed to proteins  help to regulate cell processes  transport substances into and out of the cell  help fight disease

9.  Search “Enzymes – a fun introduction” on YouTube  OR  Go to my website  Take Cornell Notes  Page: 24

10.  Take out your foldable from Thursday  Add a section for PROTEIN  On the inside of each door, write the FUNCTIONS and EXAMPLES for all three biomolecules

12.  Open to the next blank page in your journal and set it up for Cornell Notes.  Title: Enzymes  Page: 25  Date: 9-30-14  Essential question: What are enzymes?

13.  proteins that regulate cell processes  Catalyst: a substance that speeds up a chemical reaction ◦ Enzymes are biological catalysts.  speed up reactions in living things Examples include… ◦ amylase - in saliva lactase - breaks down lactose DNA polymerase – used in DNA replication helicase –used in DNA replication

14.  work best in specific conditions  help maintain homeostasis in organisms  reduce the activation energy needed in a reaction, and speed up the reaction ◦ activation energy = how much energy is needed to start a reaction

15. VERY specific perform specialized jobs have specific shapes that match or react with specific substrates (like a lock and key) Substrates = chemicals that bind to the enzyme and change in some way Draw this in your notes

17. 1 = 96 2 = 93 3 = 89 4 = 85 5 = 81 6 = 78 7 = 74 8 = 70 9 = 67 10 = 63 11 = 59 12 = 56 13 = 52 14 = 48 15 = 44 16 = 41 17 = 37 18 = 33 19 = 30 20 = 26 21 = 22 22 = 19 23 = 15 24 = 11 25 = 7 26 = 4 27 = 0

18.  Color in the question numbers you got RIGHT with a green pencil or marker.  Color in the question numbers you got WRONG with a red pencil or marker.  Answer the questions for BOTH standards. Look through your copy of the test to find “important vocabulary”.
