  1. Why does a structure like H – C = C – H fail to make sense chemically? • Differentiate between hydrogen bonding and van der Waals bonding. • If you were a pharmaceutical researcher, why would you want to learn the three-dimensional shapes of naturally occurring ligand (signal) molecules? • What does it mean that the electrons of an atom are excited? • Differentiate between dehydration synthesis and hydrolysis.

  2. List the three types of isomers we learned and give an example of each. • Differentiate between polymers and monomers. • Define functional groups. • Describe how the properties of water contribute to the upward movement of water in a tree (more than two properties apply). • How can freezing of water crack boulders? • Explain how carbonic acid can act as a buffer.

  3. Explain how the polarity of water molecule allows it to form hydrogen bonds. • Explain the following graph by relating it to the physical and chemical properties of water:

  4. When a dog pants, holding its mouth open, what property of water allows loss of heat and subsequent reduction of the dog’s internal temperature? • Describe what happens with water when it dissociates. • Compared with a basic solution at pH 9, the same volume of an acidic solution at pH 4 has ____ times as many hydrogen ions. • Differentiate between the dissociation of strong acids and weak acids. Chose which one would be a good buffer and explain why.

  5. Describe an environmental factor that results in acid rain. Explain how acid rain effects the environment and living organisms on land and in water. • Analyze the data on the given graph. How did the frequency of acid rain change over the given years:

  6. Write the chemical formula of a monosaccharide with three carbons. • Maltose forms by joining two alpha-glucose molecules together by dehydration synthesis. What is the formula of maltose? • Differentiate between the structure and function of starches and cellulose. • Describe how carbohydrates can be involved in energy storing or in providing energy.

  7. What is the group of big four that this molecule belongs to? • Which subgroup? • List four learned examples of this molecule. • List two functions of this molecule. • Determine the polarity of this molecule.

  8. What is this polymer? • Name its monomers. • Name three specific learned examples. • List two functions of this molecule.

  9. How do phospholipids polarity help them to perform their functions? • Compare the structure and function of simple lipids and phospholipids. • Draw the orientation of phospholipids in water and in oil. • Why cannot we properly digest trans fats? • How many water molecules are released when simple fats form? Why? • Why are sterols considered lipids, although they have no similarity in structure to other types of lipids?

  10. What is this polymer? • What are its monomers? • List its four functions. • Determine the polarity of this molecule.

  12. What main group of the big four does this molecule belong to? • What is this molecule? • What is its polarity? • What is its function? • What are its monomers?

  13. What is this monomer? • What is the polymer that forms from this? • How many different kinds of this monomer do we have in our body? • What is the bond that binds these monomers together? • Determine the polarity of this molecule.

  14. Name this molecule. • List two examples of this that we learned. • Name a function of this molecule. • Name the reaction that breaks this molecule down to its monomers.

  15. What is this molecule? • What are its monomers? • What is the bond that combines the monomers? • List the levels of its structure. • Name the bonds that form each level of structure. • List 5 functions of this molecule.

  16. Differentiate between the competitive inhibitor and allosteric inhibitor • Name and explain three ways in which enzyme activity can be regulated • Explain how the primary structure of proteins determine all of their other levels of structures • Why does a denatured protein no longer function properly? • What parts of the polypeptide participate in forming the secondary and tertiary structures of proteins. • Name three protein functions and describe how the protein structure fit to perform this function.
