Unit 3 Objectives: Energy in Cells: Cellular Respiration & Photosynthesis Chapters 6 and 7
There will be a quiz after chapter 6 and a quiz after chapter 7. A unit test will be on both chapters
Chapter 7 Photosynthesis
1. What is the overall equation for photosynthesis
2. Identify the following from a diagram of a leaf:
Stoma, Mesophyll cells, Epidermal cells, Veins
3. What is the function of the leaf structures above
4. Identify the following from a diagram of a
chloroplast: inner membrane, outer membrane,
thylakoid, grana, thylakoid space, stroma
5. What wavelengths (colors) of light are best for
photosynthesis?
6. What are pigments and why do we see certain
colors?
7. What is the location of the light reactions
8. Explain the process of light reactions include the role of the following:
Photosystems/chlorophyll
Movement of H+ “downhill” through ATP synthase makes
Chlorophyll energized by light
ATP
Electron transport chain
Water provides electrons giving off Oxygen
Movement of H+
NADP+/NADPH
9. What does the Calvin cycle use that was made in
14. Explain why most plants have the vast majority of
the light reactions?
their stomata on the lower epidermis of the
10. Where does the Calvin cycle occur?
leaves
11. What is the direct product of the Calvin cycle and
15. Predict what would happen if the stomata were
what can it be used to make?
open on hot, dry days and what is the problem
12. What is the role of Rubisco
with keeping them closed.
13. What goes into the Calvin cycle from the
atmosphere?
Lab: Investigation of leaf stomata, Factors influencing photosynthesis
Chapter 6: Cellular Respiration
1. List the 3 stages of cellular respiration and where
they occur
2. What is the overall equation that represents
cellular respiration?
3. Describe how breathing is related to cellular
respiration
4. Sketch a mitochondria (include matrix, cristae,
inner membrane, outer membrane,
intermembrane space)
5. What is NADH and what is its role? What is
FADH2 and what is its role?
6. The carbon in glucose leaves the cell in what
form?
7. What is produced by glycolysis?
8. What is used to get glycolysis going in the
beginning?
9. How many ATP are produced in glycolysis?
10. What electron carrier is made in glycolysis and
what happens to it?
11. Describe what happens to pyruvic acid before it
goes into the Krebs cycle
12. Identify what is produced in the Krebs cycle.
Labs/Activities: Modeling Respiration, Fermentation lab
13. Describe how ATP is made by chemiosmosis in
the ETC. Include H+, H+ pumps, locations, ATP
synthase, electron carriers
14. Explain what is meant by oxidative
phosphorylation.
15. What is the final electron acceptor in respiration?
16. How much total ATP can be produced by cellular
respiration?
17. Where is most of the ATP produced? How much
in each part of respiration
18. What happens to pyruvic acid if oxygen is
present? What if oxygen is not present?
19. Contrast aerobic and anaerobic respirations
20. What is the purpose of fermentation?
21. What are the 2 types of fermentation and what
are the products of the different types of
fermentation?
22. What is the difference between obligate
anaerobes and facultative anaerobes?
23. Are the raw materials for aerobic respiration
always glucose? Explain.
