20 Check these often: Lost and Found Lost papers

21 Monitor your Grades!!! Make sure you are monitoring your grades via HAC/SAC

22 Absent?? Check the website

23 My Goals for YOU Develop a love and curiosity for biology because biology is amazing!! Pass the AP Biology College Board Exam with a 4 or 5 (saves you time and $$$$) Have fun this year while being challenged at the college level!

24 Why I chose to teach I believe: Life should be filled with love, joy, laughter, learning and fun! One way to have these things is to get a good education and great job. The reason we are here is to help one another have these things It is important to “pay it forward” and make a difference in someone else’s life otherwise, why are we here?!?

25 The New AP Biology Course and AP Biology Exam Teacher is facilitator. Very few Power Point notes from the teacher Learning is Inquiry Based Labs are Inquiry Based Students are given objectives to meet and master.

27 AP Biology Exam – Usually 2 nd Monday in May The tests will be graded under the direction of the College Board, with scores ranging from 1 to 5. Colleges generally grant credit for scores of 3, 4, or 5, but it is up to the discretion of the participating colleges. Any student wishing to receive college credit for this course MUST check with his or her prospective college NOW to determine what will be accepted for credit.

28 Exam Information The AP Biology Exam consists of two sections: multiple choice and free response. The exam is 3 hours long and includes both a 90-minute multiple choice section and a 90-minute free- response section that begins with a mandatory 10- minute reading period. The multiple-choice section accounts for half of the student’s exam grade, and the free-response section accounts for the other half.

29 Section I, Part A, consists of 63 multiple-choice questions Part B includes 6 grid-in questions that require the integration of science and mathematical skills. In Section II, students should use the mandatory reading period to read and review the questions and begin planning their responses. This section contains two types of free-response questions (short and long), and the student will have a total of 80 minutes to complete all of the questions. There will be 2 long Free Response and 6 short free response

30 College Board Objectives and Agenda for the Day College Board: General Topics and Concepts, Biochemistry Today's Agenda- You Be the Doc Lab In this unit we will: Study carbon Learn the important biological functional groups Study organic molecules (carbs, proteins, lipids, nucleic acids) and their monomers Protein Notes Exam: Monday the 28th over biochemistry (study Cliff Notes AND Chapters 2-3 in your textbook; Visit Bozeman Biology Podcasts)

33 PreLab “You Be the Doc”

34 PPT Proteins???

35 Dehydration Synthesis Practice Everyone will start with a monosaccharide (the monomer of a polysaccharide/carbohydrate) Then you will create a disaccharide by dehydration synthesis (condensation reaction) with one partner at your table. You will have to demonstrate how a water molecule is formed in this reaction. After that, you will create a oligosaccharide by joining your disaccharide to your other partner’s disaccharide.. Once you have your oligosaccharide, you will join yours with a table near you creating a polysaccharide. Continue this until you have one large, long chain with everyone’s one your side of the room connected. Show it to me when it is done.

36 How Much Water is in a Carrot? I will put you in groups as usual Read the information regarding the lab on the handout Look at the materials on the cart Each day this week you will have 10-20 min. to work on this lab (except Wed). Some materials you will have to share. Write the materials needed and the detailed procedure you will use to extract the water. Everyone needs their own paper. Develop a hypothesis using an “if then” statement for the amount of water in the carrot and write it down. I need to approve it.

37 Proteins

38 Most structurally & functionally diverse group of biomolecules Functions: involved in almost everything enzymes structure (keratin, collagen) carriers & transport (membrane channels) receptors & binding (defense) contraction (actin & myosin) signaling (hormones) storage (bean seed proteins)

39 Proteins Structure: monomer = amino acids 20 different amino acids polymer = polypeptide protein can be 1 or more polypeptide chains folded & bonded together large & complex molecules complex 3-D shape

40 Amino acids  Structure:  central carbon  amino group  carboxyl group (acid)  R group (side chain)  variable group  confers unique chemical properties of the amino acid —N——N— H H H | —C— | C—OH || O R

41 Nonpolar amino acids  nonpolar & hydrophobic

42 Polar amino acids  polar or charged & hydrophilic

43 Sulfur containing amino acids Disulfide bridges cysteines form cross links

44 Building proteins Peptide bonds: dehydration synthesis linking NH 2 of 1 amino acid to COOH of another C–N bond peptide bond

45 Building proteins Polypeptide chains N-terminal = NH 2 end C-terminal = COOH end repeated sequence (N-C-C) is the polypeptide backbone grow in one direction

46 Protein structure & function hemoglobin function depends on structure 3-D structure twisted, folded, coiled into unique shape collagen pepsin

47 Protein structure & function function depends on structure all starts with the order of amino acids what determines that order of amino acids? lysozyme: enzyme in tears & mucus that kills bacteria the 10 glycolytic enzymes used to breakdown glucose to make ATP

48 Primary (1°) structure Order of amino acids in chain amino acid sequence determined by DNA slight change in amino acid sequence can affect protein’s structure & it’s function even just one amino acid change can make all the difference!

49 Primary (1°) structure: Sickle cell anemia

50 Secondary (2°) structure “Local folding” folding along short sections of polypeptide interaction between adjacent amino acids H bonds on backbone  -helix  -pleated sheet

51 Tertiary (3°) structure “Global (whole molecule) folding” determined by interactions between R groups anchored by disulfide bridges stabilized by hydrogen and ionic ‘bonds’ hydrophobic interactions effect of water in cell

52 2° 3°

53 Quaternary (4°) structure Joins together more than 1 polypeptide chain only then is it a functional protein

54 Chaperonin proteins Guide protein folding provide shelter for folding polypeptides keep the new protein segregated from cytoplasmic influences

55 Protein models Protein structure visualized by X-ray crystallography extrapolating from amino acid sequence computer modelling lysozyme

56 Protein structure (review) R groups hydrophobic interactions, disulfide bridges, ionic bonds R groups hydrophobic interactions, disulfide bridges, ionic bonds 4° 1° 2° 3°

57 Denature a protein Disrupt 3° structure pH temperature salt unravel or denature protein disrupts H bonds, ionic bonds & disulfide bridges Some proteins can return to their functional shape after denaturation, many cannot! Think eggs… Once you cook ‘em, there is no going back!

58 Love them Proteins!

59 Functional Group and Function Card Sort Write each functional group on a separate notecard On different notecards write the name of the functional group. One name per card. And on another card write the description. Each functional group will have three cards. EX: A card with OH, A card with Hydroxyl Group and A card that says “formed when water dissociates or falls apart also found in the structure of alcohols. Because of the hydroxyl group alcohols are....... Once your cards are created…mix them up and quiz your partner(s)
