Working in groups of two to four and armed with a textbook or some other reliable source
answer the following questions concerning organic chemistry (Chapter 3). This assignment is worth
50 points with the possible points for each question in parenthesis.
1. (2) Describe reasons why carbon is the atom of choice for macromolecules?
2. (4) Define a functional group (cite examples) and explain how when they are attached to a base
carbon atom chain how they yield different properties to the chain?
3. (4) Explain the difference between a linear vs. a monomer vs. a polymer molecule and tell which
of the following molecules: carbohydrates, lipids, proteins, or nucleic acids are polymers or linear?
4. (10) Provide the following information to describe the characteristics of a Carbohydrate.
Name the atoms found in a carbohydrate.
How are these atoms arranged to build a carbohydrate?
