  1. Give the 2 types of enzymes and their descriptions.
    • Breakers- break substrates into smaller products
    • Builders- join subtrates to make a bigger product
  2. Name the four types of macromolecules/biomoleules.
    • Carbohydrates
    • Lipids
    • Proteins
    • Nucleic Acids
  3. Carbohydrates. Give monomers, elements, function(s), and examples.
    • Monomers: monosaccharides
    • Elements: C,H,O
    • Funtion: short-term energy
    • Ex: Bread, pasta, etc.
  4. Proteins. Give monomers, elements, function(s), and examples.
    • Monomers: Amino Acids
    • Elements: C,H,O,N
    • Function: structural form for things such as hair, nails, skin, etc.
    • Ex: Chicken, steak, etc.
  5. Lipids. Give monomers, elements, function(s), and examples.
    • Monomers: glycerol; fatty acids
    • Elements: C,H,O
    • Function: long-term energy
    • Ex: Saturated and unsaturated fats
  6. Nucleic Acids. Give monomers, elements, function(s), and examples.
    • Monomers: nucleotides
    • Elements: C,H,O,N,P
    • Function: carries genetic information
    • Ex: DNA and RNA
  7. Unsaturated Fats (define)
    Fats that remain liquid at room tempurature.
  8. Saturated Fats (define)
    Fats that remain solid at room tempurature.

  9. Which macromolecule?
    Lipid

  10. Which macromolecule?
    Protein

  11. Which macromolecule?
    Carbohydrate

  12. Which macromolecule?
    Nucleic Acid
  13. Polysaccharide (define)
    Complex carbohydrate.
  14. Dehydration Synthesis (define)
    Taking away a water molecule so that a new molecule can be made.
  15. Phosphate Group (define)
    • One of the 3 parts that make up a nucleotide.
    • These make up the frame of the DNA ladder.
  16. Nitrogen Base (define)
    • One of the 3 parts of a nucleotide.
    • These make up the steps of the DNA ladder.
  17. Monomer (define)
    Small subunits which make up large molecules (polymers).
  18. Polymer (define)
    A large molecule made up of monomers.
  19. Active Site (define)
    The area on an enzyme that allows the substrate to latch onto the enzyme.
  20. Three parts of a nucleotide
    • Phosphate Group
    • Nitrogen Base
    • Pentose (Ribose or Deoxyribose) Sugar

  21. Hydrolysis (define)
    The addition of a water molecule to break a molecule apart.

  22. Glucose has a ratio of _____.
    1:2:1
