1. Explain how enzymes help to control metabolism in living organisms. Be sure to discuss what enzymes are composed of and how their structure affects their function.
2. Discuss cellular respiration:
- Name the four steps of cellular respiration.
- Give the location of each step.
- Explain how each step interacts with the other steps.
- Summarize the net energy gain of each step.
3. Discuss fermentation:
- Name the two types of fermentation.
- Give the end products of each type.
- Summarize the net energy gain of each type.
- Give examples of cells which carry out each type.
4. Discuss the two stages of photosynthesis:
- How do the light reaction and the Calvin cycle interact with each other?
- Where does each of these stages occur?
- What are the reactants and products of each of these two stages?
5. Describe the different ways that C4 and CAM plants carry out photosynthesis, when compared to C3 plants; and then explain in each case why these differences evolved.
