  1. Biochemistry Review Let’s check your understanding…

  2. State the most frequently occurring chemical elements in living things.

  3. Answer • Carbon, hydrogen, and oxygen

  4. State three other elements that are required by living things – albeit in smaller quantities…

  5. Answer • Phosphorus, nitrogen, and sulfur

  6. What word means…”carbon based compounds produced by living things”?

  7. Answer • organic

  8. Who am I?

  9. Answer • An amino acid – building block of proteins

  10. Who am I?

  11. Answer • a monosaccharide sugar – building block of carbohydrates

  12. Who am I?

  13. Answer • Fatty acid – building block of FATS/TRIGLYCERIDES. This one is a SATURATED fatty acid

  14. Who am I?

  15. Answer • Another amino acid…

  16. Who am I?

  17. Answer • Unsaturated fatty acid

  18. Who Am I?

  19. Answer • polymer

  20. Which of the following DOESN’T belong? • Glucose • Lactose • Galactose • Fructase

  21. Answer • Fructase – the rest are sugars (all end in –ose)… ending in –ase means its an ENZYME

  22. Who am I?

  23. Answer • Protein – a chain of amino acids

  24. Which element is present in maltase but not maltose? • Carbon • Hydrogen • Oxygen • Nitrogen • Calcium

  25. Answer • Maltase is an enzyme, which is a protein. Maltose is a sugar, or a carb. So, proteins have CHONS, while carbs contain CHO. So…that means that the answer is NITROGEN.

  26. Name that sugar! • used by ANIMALS for short term energy storage

  27. Answer • Polysaccharide: glycogen

  28. Name that sugar! • provides rigidity to plant cell walls

  29. Answer • Polysaccharide: cellulose

  30. Name that reaction… Monosaccharide + Monosaccharide  Disaccharide + Water

  31. Answer • Dehydration synthesis or condensation

  32. Name that reaction Amino Acid + Amino Acid  Protein + Water

  33. Answer • Dehydration synthesis, or condensation

  34. Name that reaction! Fat + Water  3 fatty acids + glycerol

  35. Answer • Hydrolysis, decomposition

  36. Name that macromolecule class! • Used for long term energy storage in animals, protection, buoyancy and insulation

  37. Answer • Lipids – specifically, fats

  38. Name that macromolecule class! • Comprised of carbon, hydrogen, and oxygen ONLY

  39. Answer • carbohydrates

  40. Name that macromolecule class! • Accounts for more than 50% of the dry mass of most cells.

  41. Answer • proteins

  42. Name that macromolecule class! • The only thing the members of this group have in common is that they are all NONPOLAR (i.e. hydroPHOBIC) and are comprised chiefly of C, H, and O (sometimes P)

  43. Answer • lipids

  44. Name that macromolecule class!

  45. Answer • lipids

  46. Name that macromolecule class! • Used for transport, protection, catalysts, cellular communications, defense against foreign substances

  47. Answer • proteins

  48. The most bang for your buck, in terms of energy, comes from…

  49. Answer • lipids
