1 Biology Warm Up Tuesday, November 9 1. Complete group evaluation form. Place completed form in blue bin by the end of class. Unit 6 Quiz This Friday

2 Behavioral Consequences 1. Verbal Warning 2. Detention + Parental Contact 3. Behavioral Interventions 4. Office Referral NOTE: All consequences are subject to a severity and discretion clause.

3 Bathroom Policy 10/10 Rule Students will absolutely NOT be allowed to go to the bathroom in the first 10 minutes or last 10 minutes of class. So don t even ask during those 10 min. periods!

4 Cell Phone Policy Electronic devices must be off and put away. If seen, they will be collected and taken to office. Electronic devices must be placed on silent and only one earbud is allowed in. If off task, the sign will be flipped to red. NO CHARGING ALLOWED If your phone is plugged up, it will be picked up.

5 Turn to page 7 of your packets. This is our Biomolecules Cheat Sheet. This will contain ALL of your notes for Unit 6. Therefore, your test will come from this one sheet. Memorize as we progress through the unit. Upcoming Events Friday: Unit 6 Quiz Tuesday: Review (You must know the cheat sheet!) Wednesday: Unit 6 Exam

6 Put down pencils! I will let you know when to pick up pencils and take notes!

7

8 What does mono- mean? Monocot Monochrome Monopoly What does poly- mean? Polyhedral Polyester Polygamy

9 Monomer one molecule or subunit Polymer many monomers linked together

10 Monomers Polymers

11

12 All contain at least one carbon atom Carbon forms four covalent bonds Likes to bond with hydrogen, nitrogen, oxygen, and other carbons!

13 What type of bond is present in all of these structures? C-H Bonds!!

14 Made up of C, H, O,

15 What are does the the monomers name carbohydrate of a carbohydrate? mean? Monosaccharides Carbo from Carbon (C) What does mono mean? What is a saccharide? Hydrate from Water (H2O) One Sugar or Simple Sugar!

16 Many monosaccharides are isomers of each other What is the ratio of carbons:hydrogens:oxygen? So what are isomers? 1:2:1 Compounds with the same molecular formula (same number of atoms) but different structural formula Different structural formula Same molecular

17 If a monosaccaride is one sugar, what are Disaccharides? Sugars made up of two monosaccarides Table Sugar Two Monosaccharides Disaccharide

18 What are Polysaccarides? Many sugars! AKA Complex Carbohydrates Includes: Starch Glygogen Celluose Used Cellulose for energy has a (ATP) Used different storage for energy type in of animals (ATP) bond. storage The long chains Animals in plants of monomers actually Animals cannot link break break to each down it Animals down- glycogen this other. Primary to is consume obtain the fiber structural quick and in molecule energy(atp) your break diet! in down plants. Cell from starch Walls!! glucose to obtain glucose

19 Pick up pencils!

20 Let s Review Carbohydrates! Elements: Carbon, Hydrogen, Oxygen Ratio of Elements: 1:2:1 (C:H:O) Monomer: Monosaccharides Polymer: Disaccharides, Polysaccharides Function: Quick, Short-Term Energy (ATP)

21 What is ATP? Adenosine triphosphate The molecule living things use on Earth use to carry energy! So ATP = ENERGY

22 Let s Review Carbohydrates! Elements: Carbon, Hydrogen, Oxygen Ratio of Elements: 1:2:1 (C:H:O) Monomer: Monosaccharides Polymer: Disaccharides, Polysaccharides Function: Quick, Short-Term Energy (ATP) Examples: Glucose, Starch, Glycogen (often end with ose) Picture: RINGS!

23 Put down pencils!

24 LIPIDS

25 Examples of Lipids Oil Adipose Tissue Cholesterol (stores fat in (waxy body) steroid)

26 Lipids: How They re Made Made up of C, H, O

27 Lipids: How They re Made Lipids are hydrophobic (repel water) 1 glycerol and 3 fatty acids make up the polymer of a lipid (formed in dehydration synthesis)

28 Dehydration Synthesis of Lipids (fats)

29 Polymer of Lipids 3 Fatty Acids 1 Glycerol

30 Fats are also known as triglycerides!! Made of 1 glycerol and 3 fatty acids all attached by dehydration synthesis Do you see the E shape?

31 Saturated Fats Contain no double bonds between carbons Carbons are saturated with hydrogen

32 Saturated Fats Shape is smooth and straight Solid at room temperature Examples: Butter Lard

33 Unsaturated Fats Contain double bonds between carbons

34 Unsaturated Fats Double bonds cause shape to crinkle Liquid at room temperature Example: Oil

35 Phospholipids Major component of cell membranes Form a phospholipid bilayer membrane.

36 Phospholipid s special structure

37 Other Lipids Waxes: form hydrophobic coating to repel water or reduce water loss Steroids: lipids bent into rings ex: Cholesterol

38 Pick up pencils!

39 Let s Review Lipids! Elements: Carbon, Hydrogen, Oxygen Two Parts of Molecule: Glycerol, Fatty Acids Shape: Long chains and/or E shape Part of which cell structure: Cell Membrane! Function: Slow, Long-term Energy (ATP) Stores the most energy! Examples: Fats, Oils, Phospholipids (cell membrane), waxes, etc. Picture: Chains or M shape E

40 Incomplete Practice 1. Complete Group Survey & Turn In. 2. Complete Carbohydrate/Lipids Review WS. Due TODAY Turn into Basket Upcoming Events Friday: Unit 6 Quiz Tuesday: Review (You must know the cheat sheet!) Wednesday: Unit 6 Exam
