1. HONORS Warm-up 1.Turn in your “virus” reading assignment. 2.Complete the Unit 2 Biochemistry Vocabulary Pre-assessment by marking your level of understanding of each term in the middle column. 3.When you finish, read over the learning objectives on the back page.

2. Homework Tonight 1.Complete pp. 11-13 (through the “check yourself”) in the Biology Handbook 1.You will need to go online to the class website and open or download the filled in version of Unit 2 in the Biology Handbook in order to complete some of the blanks. 2.Answer all the questions on the side and the questions at the end! 2.Your Unit 1 Study Guide is Due Friday 3.Study your notes on Scientific Method and Characteristics and Processes of Living Things (STERNGRR) for your TEST on FRIDAY.

3. Introductory Lab: Using Cabbage Indicator to Determine pH Read the introduction information about the pH scale silently to yourself. Now answer the pre-lab questions on your own. Once you have your own answers, compare your responses with those of someone else at your table.

5. Safety Precautions Be careful. These are REAL acids and bases that can cause damage to eyes, skin, and clothing if not handled with care. Goggles and aprons are available. At the end of the lab, you may wash your hands. Only ONE PERSON should be away from your lab table at any time. This person is getting materials from me!

6. Answer the “Analysis” Questions at the end when you have completed the lab.

7. Unit 2: Biochemistry! Read the information on the left. Highlight! Answer the questions on the right.

8. Happy Thursday 1.Take out your Unit 1 Vocabulary and Learning Objectives Sheet. –Rate your understanding of each term (0-4) in the “after instruction” column. 2. Have out your homework (Handbook p. 11-13) Be prepared to discuss the role of “buffers” in living things.

9. STERNGRR = Life Processes STERNGRR is all of the things (processes/functions) a living thing DOES. They are not characteristics (we learned the 6 characteristics of life…) Quick Partner Vocabulary Matching Exercise!

10. Housekeeping Remember the class website: http://Lindsaymathisbiology.weebly.com http://Lindsaymathisbiology.weebly.com Remember that Study Guides are Due Tomorrow (check the rubric!!!) Unit 1 Test Tomorrow! No additional homework tonight. Be sure to get caught up if you are behind!

11. Chemistry of Life Introduction to Biochemistry What are elements? What are elements? http://www.youtube.com/watch?v =Uy0m7jnyv6U http://www.youtube.com/watch?v =Uy0m7jnyv6U

12. Atoms, Matter, Elements, Compound 1.Life is composed of matter = anything that has mass and takes up space. 2.Atoms are the smallest piece of matter. 3.Matter composed of only one kind of atom is called an element. These substances cannot be broken down into other substances. 4.Compounds are substances containing two or more elements. Examples include water, chlorophyll, and glucose (C 6 H 12 O 6 ).

13. How do atoms form larger molecules like compounds? When 2 or more atoms come together they will join together to create larger molecules and compounds. When the two particles get close together they join or bond. This creates a chemical bond. Energy is then stored in those bonds. So, as more and more atoms are bonded together, more and more energy is stored. Bonding is the basis of all energy conversions in living things!

14. A Closer Look at Energy (not in your notes!) What do all of these pictures have in common? ENERGY!

15. Energy BREAKING BONDS RELEASES ENERGY FORMING (MAKING) BONDS STORES ENERGY

16. One more thing In living things, ENERGY is STORED (bonds are formed) during In living things, ENERGY is RELEASED (bonds are broken) during Photosynthesis (and growth, development) Photosynthesis Respiration (and digestion, metabolism) Respiration

17. Why are molecules important? Molecules store energy and make up living things like us! Our food is made of molecules like proteins, carbohydrates, lipids (fats), and water. a)What happens to the molecules of food when you digest them? What is released? ENERGY! b ) This energy is used to perform important life processes like growth, digestion, metabolism, and synthesis of new molecules, tissues, and body parts. It also takes energy for your body to perform digestion. Your body temperature is a constant reminder of metabolism at work!

18. Example of a carbon dioxide molecule What is holding the carbon and oxygen atoms together? bonds These store Energy! Bonds are represented by the lines.

19. Below are some pictures of different compounds and molecules. Circle the molecule that would likely provide the MOST energy to a living organism? Explain why:

20. ORGANIC Chemistry = BIO chemistry = Chemistry of LIVING Things NOVA : “Ingredients for Life: Carbon” NOVA : “Ingredients for Life: Carbon”

21. Compound = a substance made up of two or more elements Living things are made up of 2 types of compounds INORGANIC Compounds - Compounds that do not contain (C-H) CARBON-HYDROGEN bonds - Found in both living and non- living things - NON-Living = Abiotic Examples: NaCl (table salt) H 2 O (water) CO 2 (carbon dioxide) What else can you think of? ORGANIC Compounds - Compounds that DO contain CARBON-HYDROGEN (C-H) bonds - Found ONLY in living things - Living = Biotic Examples: C 6 H 12 O 6 (glucose/sugar) CH 4 (methane)

22. Practice: Observe the following chemical structures of each compound. Determine if it is organic or inorganic? What elements should you look for? Carbon AND Hydrogen. Circle all the organic compounds.   The ones I circled are ORGANIC because   Organic compounds would be found only inside __________________ things.

23. Review! 1) Is this molecule O RGANIC or I NORGANIC? WHY?

24. Review! 2) What do the lines in this picture represent? What is stored in these lines/bonds?

25. Review! 3) Is this compound O RGANIC or I NORGANIC? WHY?

26. Review! 4) Which compound/molecule has the MOST stored energy? AB WHY?

27. Review! 5) Is this molecule O RGANIC or I NORGANIC? WHY?

28. 4 Organic Compounds: 1.CARBOHYDRATES 2.LIPIDS 3.PROTEINS 4.NUCLEIC ACIDS Video: “The Biomolecule Band” “The Biomolecule Band”“The Biomolecule Band”

29. Polymer = Complex Complex = Large Monomer = Simple Simple = Small A POLYMER is a LARGE molecule. It is called a POLYMER because it is made up of many smaller units. Those smaller units are called MONOMERS. Monomers are the building blocks of all organic compounds. Carbohydrates, lipids, proteins, and nucleic acids are all examples of organic polymers, and they are all made of smaller subunits or monomers.

30. Polymer = Complex Complex = Large Monomer = Simple Simple = Small

31. Organic Molecules Foldable To start, you will need: 4 sheets of paper Glue Markers or colored pencils Listen and watch as I model how to fold the papers.

32. The Setup: Each quadrant = one organic macromolecule 1.CARBOHYDRATES 2.LIPIDS 3.PROTEINS 4.NUCLEIC ACIDS

33. First “unfolding” ELEMENTS BUILDING BLOCKS (monomers) (monomers)

34. Second “unfolding FUNCTIONS EXAMPLES / TYPES INDICATOR / TESTS PICTURES Cut from magazines, advertisements, internet, etc

35. Your Task Each group will receive a folder with information cards about each of the 4 molecules. You will use these cards to fill in information about each molecule. Pay close attention to words in ALL CAPS. Include the most important information Do not keep or write on the info sheets Use bullets and lists, not sentences Use color!
