Presentation Transcript

  1. Study guide answers • Building blocks • Carbohydrates, lipids, proteins, nucleic acids • Carbon 4. Carbon / hydrogen 5. They can stack like bricks, form lines, etc.

  2. 6. CHO’s – monosaccaharide Lipid – fatty acid glycerol, phosphate * no true monomer Proteins – amino acids Nucleic acids – nucleotides • Many monomers bonded together • Chains, rings, branches • -OH, -PO4, -COOH which are hydroxyl, phosphate, carboxyl Their structure make them function

  3. Arrangement of atoms-shape-structure • Have carbon, few elements, have monomers, form determines function 12. To store energy, polymers are formed • Carbon, hydrogen, oxygen 1:2:1 • Monosaccharides • momomer -fructose, glucose, galactose 16. Ring structured carbon molecule 17. 2 monosaccharides bonded together – sucrose, lactose, maltose

  4. 3 or more monosaccharides bonded • Glycosidic bond 20. startch, glycogen, cellulose • Starch 22. Glycogen 23. Structure in plants cell wall • Store quick energy in the form of glycogen on the muscle • Fatty acids, glycerol, phosphate groups • Steroids – cholesterol, estrogen, testosterone Oil/fats and waxes

  5. Carbon/hydrogen chain with a carboxyl group on the end • has single bonds between carbons • fats/oils – store energy Waxes – waterproof Steroids – chemical messengers 30. Be able to identify – triglyceride, phospholipid, steroid • Same • to make cell membranes

  6. Hydrophobic -None polar molecules –– don’t dissolve in water • Not soluble in water but are soluble in lipids • papertowel leaves translucent spot –ethanol it dissolves lipids • form muscles, transport oxygen, make hormones, act as enzymes • muscles, enzymes, hormones, hemoglobin • Amino acid • peptide

  7. 40. 20 41. R group 42. R group 43. primary, secondary, teritary, quaternary protein color sheet 44. pH and temperature 45.DNA & RNA 46. Store and transmit genetic info. And cellular activities like make proteins 47. RNA is a copy and can leave the nucleus to make proteins 48. nucleotide

  8. 49. 5 carbon sugar, a phosphate group, nitrogen base • Twisted ladder/ double helix • sugar/phosphate • hydrogen bonds between nitrogen bases • Adenine, guanine, cytosine, thymine • rungs • Thymine

  9. 56. DNA cannot leave nucleus Is double stranded Has thymine Deoxyribose sugar RNA can leave the nucleus Is single stranded Has uracil Ribose sugar

  10. Similarities Made of nucleotides Start in nucleus Both nucleic acids Both complemenetary base pair Both store and transmit information

  11. Chapter 3 Test Answers • E • H • F • G • A • C • B • D • T • F influences the chemical properties of a compound • T • F during the condensation reaction (dehydration synthesis) • T • D • D • A • B • B • C • A • C • B • B • 1 oxygen and 2 hydrogen are bonded at an angle because of an uneven distribution of electrical charge – it’s a polar molecule • Condensation reaction is removing 1 water molecule to join monomers and hydrolysis is adding one water molecule to break apart polymers • Monosaccharides – simple sugar – monomer, Disaccharides – 2 monosaccharides bonded, Polysaccharides – 3 or more monosaccharides bonded • Shape is determined by the way the protein’s amino acids interact with one another. These interactions cause proteins to bend or fold. There shape may be altered by pH or temperature • The polar hydrophilic heads make the interior and exterior surface of a cell membrane • 1st Double bonds between all carbon atoms 2nd double bond between carbon atoms 3rd double bonds between the two horizontal carbon atoms • A. Disaccharide b. Fatty acid c. Water d. Dipeptide e. nucleotide

  12. Macromolecules worksheet #2part A • CHO • Lipid • Lipid • CHO • Nucleic acid • Nucleic acid • Protein • CHO • Lipid • CHO • Lipid • Lipid • CHO • CHO • Protein • Protein • Lipid • Nucleic acid

  13. Macromolecules worksheet #2 Part B • lipid • DNA • Glucose • Steroids • Starch • Protein • Phospholipids • Enzymes • Monosaccharides • Glucose • Amino acids • Oils • DNA • Cholesterol • Glycerol • Glycogen • Polysaccharide • Nucleotide • cellulose
