Directions: Use the diagram above to answer the following questions.
1. Write the 2 reactants and 3 products of cellular respiration. (Reactants are going in, Products are being produced)
2. Cellular Respiration occurs in three steps. From the diagram above, what are the names of the three
steps?
3. What is the reactant in step 1 that is also a product of photosynthesis?
4. Specifically, where does glycolysis occur in the cell? What is the product of Glycolysis that is used in
the next step?
5. What must be present for the next two steps to occur? Where do the other two steps occur?
6. When is carbon dioxide (CO2) produced?
7. Where does the carbon (C) in carbon dioxide (CO2) come from? The oxygen (O)? 8. NADH and FADH2 are molecules that carry electrons. In which steps are these molecules produced?
9. What is the purpose of the first two steps?
10. To which step do NADH and FADH2 carry the electrons?
11. What are 1 reactant and 1 product from the Electron Transport step?
12. Oxygen molecules attract electrons. What do think the function of oxygen is in the electron transport
step?
13. Where does the oxygen (O) go after it has done its job?
14. Where does the hydrogen (H) from the glucose molecule go?
15. How many ATP molecules can be made for every glucose molecule? Which step produces the most
ATP?
