Be sure you understand and can explain the following concepts:
1. What is the purpose of an enzyme? Be able to label the substrate, enzyme, products,
and active side on a diagram.
2. Explain the lock and key model. How does an enzyme do its job? How does the lock and
key model differ from the induced fit model?
3. What factors can cause an enzyme to denature? Describe what a denatured enzyme
looks like. Can a denatured enzyme repair itself? If so, how?
4. What is the purpose of photosynthesis? Where is it performed? Which types of cells
perform photosynthesis?
5. What factors can influence the rate at which photosynthesis occurs?
6. What is the purpose of cellular respiration? Where is it performed? Which types of cells
perform cellular respiration?
7. Explain the importance of ATP.
8. Be able to write/identify the formulas for photosynthesis and respiration.
9. Explain the relationship between photosynthesis and respiration.
10. What type of respiration occurs in the presence of oxygen? Without oxygen?
11. Which form of respiration is most efficient? How do you know?
12. Where does alcoholic fermentation occur? What is produced as a byproduct?
13. Where does lactic acid fermentation occur? What is produced as a byproduct?
14. Which process evolved first - aerobic or anaerobic respiration? How do you know?
