Reading Guide—Photosynthesis and Cell Respiration
Levasseur
Answer the following questions in complete thoughts on your own paper.
Section 8.1
1. Why do you need energy? Where does your energy come from?
2.
What is ATP? What is ADP? Compare them to a battery.
3.
List three uses for ATP in the body.
Section 8.2
4. Photosynthesis occurs primarily in plants. The sunlight is absorbed by pigments. What is the main pigment that absorbs the
light?
5.
Which color of light is absorbed the most? Which the least? How does this explain the fact that plant leaves are green?
6.
Draw and label the parts of a chloroplast and explain the function of the thylakoids and stroma.
7.
Write the equation for photosynthesis. Explain the equation in a sentence.
8.
Draw the chart below. Compare and contrast light-dependent (light) and light-independent (dark) reactions.
Light-dependent
Similarities
Light-independent
Section 8.3
9. Summarize what happens during light-dependent reactions. What is used and what is produced?
10. Summarize the Calvin Cycle as it occurs in light-independent (dark) reactions. What is used and what is produced?
11. Explain how temperature, light, and water are important factors that affect photosynthesis.
Section 9.1
12. Define cell respiration in your own words.
13. What two molecules are necessary for cell respiration to occur? What waste molecules get produced? Where in the cell
does cell respiration occur?
14. What part do you suppose enzymes play in the process of cell respiration?
15. Explain in your own words, why we require so much oxygen in order to survive.
Section 9.2
16. Why is glycolysis an important process in the cell?
17. Cell respiration is broken down into three steps (glycolysis, Krebs cycle, and electron transport). Look at the diagram on
page 260. What is the total number of ATP molecules generated by cell respiration?
Section 9.3
18. Draw the chart below. In living organisms, when there is no oxygen present, glucose is broken down in a process called
fermentation. Compare and contrast lactic acid fermentation to alcoholic fermentation. Include types of organisms.
Lactic Acid Fermentation

19. Draw the chart below. Use a compare and contrast fermentation to normal cell respiration.
