Ch3_The molecules of life_ organic compounds by nuhman10


									STUDY GUIDE

Recommendations to follow:
   1.   Answers are thought to be short in most of the cases
   2.   Try as much as you can to connect the terms and understand the association between some of the concepts in order
        to get the whole picture about the topic. Memorizing alone can give you probably around a 70/100 in the exam, but
        some questions always require to connect two or more ideas to come up with a short and precise answer.
   3.   If you understand these review questions you should do fine in the test, questions in the test will variations of the
        same themes covered in these questions.

Ch3_The molecules of life, organic compounds
  1. What is the difference between organic and inorganic molecules? Which atoms are commonly found in
     organic molecules?
  2. What determines the chemical properties of organic molecules, in other words, the way they will react or
     not to certain chemicals, or whether or not they will dissolve in water?
  3. What is the difference between macromolecules and normal organic molecules?
  4. Name the four (4) main organic molecules present in living things. Which important organic molecule does
     not constitute a macromolecule?
  5. What kind of carbohydrate do plants use to store energy? What about animals? What type of carbohydrate
     is the main component of the cell walls in plants?
  6. What is the monomer (molecule that acts as a unit) of proteins?
  7. Name the main functions that proteins may have in living things
  8. How many different amino acids exist?
  9. How many structures can be defined for a protein? Differentiate between primary and secondary structure
  10. What is the monomer (molecule that acts as a unit) of nucleic acids? What kind of molecules are parts of a
  11. What types of nucleic acids exist? What is the function of each one?
  12. State the main structural and molecular differences between DNA and RNA?
  13. Lipid is, in fact, the general definition for several different molecules. Name the three types of lipids
      detailed in the handouts.
  14. What is the difference between a saturated fat and an unsaturated one?
  15. Lipids are a very efficient way to store energy in the body, but they are the second source of energy. The
      first one are carbohydrates. How does the efficiency of lipids compare to that of sugars? (handouts)
  16. Molecules that work as hormones and are lipids are…? And they belong to what group of lipids?
  17. What kind of lipid is the cholesterol?
  18. What type of lipid is a main component of the cell membrane? These molecules are polar in one extreme
      and non polar in the other, what part is polar and which one is non polar?

                                                                                                    Instructor: Dr. Jose Bava
