1). How is the basic functioning of enzymes affected by its shape, active sites and interaction with specific molecules and the environment?

2). Describe and compare the roles of CO2 and H2O in photosynthesis and cellular respiration.

3). A certain poison inhibits an enzyme involved in the Calvin cycle, preventing a cell from completing the Calvin cycle. Explain what effect, if any, this would have on the cell's ability to complete the light reactions of photosynthesis. (Hint, if needed: Think about any molecules or ions that cycle back and forth between the light reactions and Calvin cycle).

4). Compare exergonic and endergonic reactions in terms of energy, and give an example of each type of reaction.
