  19. 1. What is the chemical formula for glucose? • C6H12O6

  20. What colour molecule is deoxyribose • red

  21. a 3. This is a phospholipid membrane, indicate which end is hydrophilic (a) and hydrophobic (b). b

  22. 4. What class is this carbohydrate? Polysaccharide 5. Give three examples of this class of carbohydrate. Cellulose, glycogen, starch

  23. 6. Name the type of molecule pictured. 7. What colour is the amine group? Amino acid ORANGE NH2 http://alevelnotes.com/Amino-Acids/59

  24. 8. What is denaturation? A change in shape of a protein 9. How can it occur? When a cell is exposed to high temperatures or a unfamiliar pH.

  25. 10. How is glucose broken down? Aerobic respiration C6H12O6 + 6O2 6CO2 + 6H2O ATP (energy released)

  26. 11. Name this test. • starch http://www.sciencephoto.com/media/4381/enlarge

  27. 12. What type of macromolecule is Keratin? • Protein

  28. 13. which fatty acid is the most highly saturated? http://revisionworld.co.uk/a2-level-level-revision/biology/core-principles-foundation/biological-molecules/lipids

  29. 14. What subunit of a nucleotide molecule changes? • N containing base

  30. 14. Which disaccharide is being formed. • Sucrose 15. What type of reaction is used. • Condensation

  31. 16. What macromolecule is found on the surface of a cell and is responsible for repelling water. • Waxes

  32. 17. How does the structure of RNA different to DNA? http://www.biologycorner.com/bio1/DNA.html DNA have 2 chains of nucleic acids and has AGCT nitrogen containing groups. RNA is a single chain and as AGCU nitrogen containing groups. DNA has the sugar deoxyribose, RNA has the sugar ribose.

  33. 18. What type of bond links amino acids to create a protein? • Peptide

  34. 19. Where in the cell is DNA found? • The nucleus, mitochondria and chloroplast.

  35. 20. What are the health effects of a high lipid diet? Give an example. http://www.helpingyoucare.com/15813/denmark-imposes-fat-tax-on-high-saturated-fat-foods-to-combat-obesity • Saturated fats can lead to heart disease and clogged arteries, due to an increase in cholesterol (sterol)
