1. What are the four classes of biological macromolecules? For each of the four classes, tell a) what they are made of (what's the monomer or building block), b) what they're used for, and c) give one example of each found in the human body (not a food!)
2. In what way are all four groups similar in chemical composition, and how do they differ? (i.e., why are they called organic molecules?)
3. An individual can die after experiencing a high fever for a prolonged period of time. Using what you know about enzymes (they are proteins), explain why an individual who enters the emergency room with a high fever might be given an ice bath to lower his or her temperature.
