Acids Bases and pH


Part 1: Chemistry

Questions to answer:

  1. How common are the elements that living systems are made out of?
  2. Explain the relationship between matter and energy.
  3. Why do atoms bond?
  4. What is the cause of molecular polarity?
  5. How does the type of bonds present in a substance influence the chemical and physical properties of that substance?
  6. If the breaking of bonds requires an input of energy (which it always does), how is it possible that some chemical reactions (like the burning of gasoline, for instance) can release energy into the environment?
  7. How do the properties of a compound like H2O or NaCl illustrate the concept of emergent properties?
  8. Why are radioactive elements useful for the study of biological systems?

(feel free to ask questions about them in class)


Part 2:  Water

Questions to answer:

  1. Why are living things mostly made of water?
  2. Draw a water molecule and indicate its polarity.
  3. Explain how the structure of water molecules account for each of the following properties:
  1. Cohesion
  2. Adhesion
  3. High Specific Heat
  4. Floating Ice
  5. Good Solvent Properties
  6. Dissociation of water molecules
  1. Explain 1 way that each of the above properties are useful for living systems.
  2. Explain the relationship between the dissociation of water and the pH of a particular aqueous solution.

Part 3:  Carbon

Questions to answer:

  1. Why is carbon central to the structure of all biological molecules?
  2. Explain the concept of an isomer.  As the number of carbon atoms in a molecule increases, what happens to the number of possible isomers of that molecule?
  3. Why is it significant that all biological systems use L-amino acids and D-sugars?
  4. Draw each of the following functional groups:
  1. hydroxyl
  2. carbonyl (ketone)
  3. carbonyl (aldehyde)
  4. carboxyl
  5. amino
  6. sulfhydryl
  7. methyl
  8. phosphate
  1. Why are molecules that contain carboxyl groups acidic?  
  2. Why are molecules that contain amino groups basic?
  3. How large a change to the structure of an organic molecule has to be made for that molecule to have a major difference in its effect on a living system?
