What are the reactants?
What are the products?
Where have you seen something like this before? Explain.
3. How does the equation for cellular respiration compare with the equation for
photosynthesis?
4. What is ATP? Why is it an important product of cellular respiration?

Part 3. The Importance of Oxygen
8. What is the difference between anaerobic and anaerobic respiration?
9. What is lactic acid fermentation? Where does it occur?
10. What does a build-up of lactic acid cause?
11. What is alcoholic fermentation?
12. Why would an organism prefer aerobic respiration as opposed to anaerobic respiration
(fermentation)?
Part 4. Tying It All Together
13. Give three ways that photosynthesis and respiration are dependent on one another.

molecules.
b. Water molecules and radiant energy are necessary for anaerobic respiration to
take place.
c. Oxygen molecules release energy in the form of heat during combustion
reactions.
