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
