3. Reminders Biochemistry Root words given out Thursday- Quiz Tues, 9- 29-15 Biochemistry Review packet 1 given out Thursday test date Wednesday, 9-30-15 Review packets: Atoms and Nature of Matter given out Tuesday. ALL are DUE TEST DAY Read chapter 6 Test and Quiz make ups, tutoring during PLC on TUES and THURS ALWAYS sit in your assigned seat!!! Refer to your Science Rules and Procedures Class brochure for retest policy and other impt. information Next Science Fair due date ~ 10-9-15 and will be the final draft of your background research report.

4. Quick Review Monomers are small single subunits or building blocks that form polymers. Examples of monomers and polymers include: 1. amino acids are the monomers for proteins/polypeptides 1. amino acids are the monomers for proteins/polypeptides 2. nucleotides are the monomers for nucleic acids (RNA/DNA) 2. nucleotides are the monomers for nucleic acids (RNA/DNA) 3. monosaccharides are the monomers for carbohydrates/polysaccharide 3. monosaccharides are the monomers for carbohydrates/polysaccharide Monomers are joined together to form polymers by a chemical reaction called Dehydration Synthesis or also known as a Condensation Reaction. Polymers are broken down into their monomers (digestion) by a reaction called Hydrolysis by a reaction called Hydrolysis *Water is the important link in both reactions!!!

5. Quick Review Monosaccharides are the monomers that make up Carbohydrates.Carbohydrates are used for quick energy. They are sugars and starches. They can be found in plant cell walls in the form of cellulose, in fungi cell walls and exoskeletons of insects as chitin and in liver & muscle cells in the form of glycogen. Glycerol and fatty acids are the monomers that make up lipids. Lipids function as: long term energy storage, insulation, water proof covering (plant leaves) and some hormones (such as Estrogen and Testosterone = gender Hormones), and they serve as the major component of cell membranes).

6. Quick Review Amino Acids are the monomers that make up proteins. Proteins have a lot of functions in the cells, tissues, organs, organ systems and organism! They provide structure, allow for transport of things into and out of the cell, make up many hormones and your immune system. They are your skin, hair, nails, they carry oxygen in red blood cells throughout your body. Among many other things.

7. QUIZ Clear your desks of everything Do NOT write on the quiz please Use CAPITAL letters please Keep your answers covered If you need to make up a quiz due to an absence… Tues and Thurs during PLC Flip it over when you are finished and hang on to it.

8. Today’s Objective: Objective: Biochemistry and organic compounds. Formation of monomers into polymers by Dehydration synthesis. The breakdown of polymers into monomers. Carbohydrates, Lipids and proteins- structures and functions.

10. EcoRegion Project Presentations Ms. Eaves’ Classes Part of your grade will be based on your presentation and your attention during your classmates’ presentations. Hand me your rubric when you come up to present.

11. Ecology Peer Evaluations- Eaves’ Classes On the top left of your paper please PRINT all group members names (first & last) On the top right of your paper please PRINT your name Divide your paper into three sections (one section for each of your partners and one section for your self evaluation). Write your partner's names above one of the sections and your name above the last section) Answer these questions using COMPLETE SENTENCES about each partner in their section of your paper and about yourself in your section. 1. Did your partner complete their assigned section of your presentation? 2. Did your partner complete their assigned section on time? 3. Did your partner use their class time wisely? 4. Do you think your partner adequately explained their section? Why or why not? 5. Did your partner include video clips and diagrams or any additional material for their section? 6. What grade do you think your partner deserves AND WHY? **DO NOT let anyone see your evaluation. Bring your paper to me.

12. Organic Molecules ppt & Foldable Let’s finish the power point Nucleic Acids Foldable Journals
