  1. Who Am I?

  2. Whiteboard:Group Member #1A1, B1, C1, D1, E1, F1, G1, H1

  3. Chlorophyll • the green pigment in plants that captures light in photosynthesis

  4. DNA • has deoxyribosesugar • has nucleotides A, T, C, G • inherited genetic material that contains instructions for life • double-stranded

  5. Protein • macromolecule made of amino acids • contains C, O, H and N • found in muscles • used for growth and repair

  6. Ion • examples: H+, OH- • an atom with a positive or negative charge • # of e- does not equal # of protons • lost or gained e-

  7. Inorganic Compound • compounds that do not contain C and H • don’t come from living things • examples: NaOH, FeO

  8. Enzyme-Substrate Complex • when an enzyme is bound to an appropriate substrate and bonds are being broken and reformed • combination of enzyme and substrate

  9. Carbohydrate • a macromolecule that has H and O in the same ratio as water, as well as carbon • ‘hydrated carbons’ • examples: sugar, starch, cellulose, chitin

  10. Organic Compound • compounds containing C and H • come from living things • examples: sugar, nucleic acids

  11. Disaccharide • Example: lactose • two linked sugars • formed through a dehydration synthesis reaction

  12. Substrate • example: H2O2 in our liver lab • molecule(s) that is changed by an enzyme

  13. ATP (Adenosine Triphosphate) • found in all organisms • stores energy released from cellular respiration • important energy transfer compound in organisms

  14. Chemical Bond • represented by lines in models • the forces that hold atoms to one another in molecules

  15. Chemical Reaction • example: photosynthesis changes CO2 and H2O into C6H12O6 and O2 • a process that changes one set of chemicals into another

  16. Whiteboard:Group Member #2A2, B2, C2, D2, E2, F2, G2, H2

  17. pH Scale • ‘power of hydrogen’ • measure of H+ ions, acidity • ranges from 0 - 14

  18. Polysaccharide • formed through many dehydration synthesis reactions • many linked sugars • complex carbohydrates • examples: starch, chitin, cellulose

  19. Polypeptide • will be folded into a protein • long chain of many linked amino acids

  20. Starch • used in Inv. 4.4 & 4.5 • complex carbohydrate used for energy storage in plants • type of polysaccharide

  21. Fat • type of lipid made up of fatty acids and glycerol • used for energy storage, cushioning, insulation

  22. Compound • examples: H2O, CO2, H2O2 • two or more elements bonded together

  23. Cholesterol • a type of lipid made by animals • found in cell membranes

  24. Nucleic Acid • macromolecule that carries genetic material • basic unit is nucleotide • examples: DNA, RNA

  25. Atom • the basic unit of matter • composed of protons, neutrons, and electrons

  26. Monosaccharide • example: glucose • simple carbohydrates • a single molecule of sugar • can be linked together to form disaccharides

  27. Decomposition • breaking down or taking apart • example: when H2O2 was broken down in our liver lab

  28. Hydrolysis • example: decomposing starch into glucose) • the breaking of bonds by adding water

  29. Carbon Cycle • how carbon is exchanged through the environment • includes photosynthesis & cellular respiration

  30. Electrons • have very little mass • negatively charged particles around the nucleus of an atom

  31. Whiteboard:Group Member #3A3, B3, C3, D3, E3, F3, G3, H3

  32. Matter • a physical substance that has mass and takes up space • can be classified as solids, liquids, or gases

  33. Acid • example: HCl • solution with lots of H+ ions • pH from 0 - 7

  34. ADP • ATP that has had a phosphate removed to release energy Released Energy

  35. Synthesis • to combine or put together

  36. Neutrons • neutral particles found in the nucleus of an atom

  37. Element • more than 100 types • pure substance made of one type of atom • arranged according to properties in the periodic table

  38. Randomness/Disorder • the idea that non-livings are always moving to a state of _____________ while living things, on the other hand, invest energy to create organization

  39. Photosynthesis • requires chlorophyll to capture light • process used by plants to create sugar using light energy

  40. Fatty Acids • chain of linked carbons with many H bonds • component of lipids, in addition to glycerol

  41. Buffering Capacity • the ability to resist a change in pH

  42. Base • Example: NaOH • solution with los of OH- ions • pH 7 - 14

  43. Neutralize/Neutralization • combining an acid and a base to form water

  44. Amino Acids • basic unit of proteins • 20 types that are essential • linked together to form polypeptide chain

  45. Cellulose • type of polysaccharide • complex carbohydrate used as building material in plants • found in the cell walls of plants

  46. Poly- • prefix meaning many

  47. Whiteboard:Group Member #4A4, B4, C4, D4, E4, F4, G4, H4

  48. Buffer • any substance that resists a change in pH

  49. Molecule • smallest unit of a compound • multiple atoms bonded together • Examples: O2, H2O

  50. Mono- • prefix meaning one
