Photosynthesis and Cellular Respiration Test Review
This test will cover
all material from the photosynthesis and cellular respiration unit. Make sure to review ALL materials- notes,
quizzes, labs and homework assignments in order to prepare. Study all of these items several times BEFORE
completing the test review questions below. This way, you can really see what you know and what you need to
study more. Using your notes to fill in blanks and answer questions without studying first will NOT help you on your
test!

Use EXTRA PAPER and write out full answers!!!!!
2. Where does lactic acid fermentation take place in humans? How long can a human survive using anaerobic
respiration? Why? Explain fully- make sure to explain the significance of oxygen as the final electron acceptor....
3. Fully describe the electron transport system and the process of chemiosmosis IN YOUR OWN WORDS.
4. What do bread and wine have in common, in terms of respiration? Explain how bread is made and why you
don’t actually consume alcohol when you consume bread.
5. How are photosynthesis and cellular respiration related? You should start answering this by using equations.
6. What is a facultative anaerobe? Explain how the consumption of carbohydrates increases when yeast are deprived
of oxygen.

10.
Can organisms produce more ATP with aerobic or anaerobic respiration? EXPLAIN!
What is the overall purpose of the Kreb’s cycle?
What is the overall purpose of the ETC in CR?
What is happening EXACTLY when your body runs out of oxygen during exercise (think beyond simple lactic
acid production- include the terms pyruvate, NAD+ and final electron acceptor in your answer).
11. Explain what makes an object appear a certain color.
12. What pigments are used in photosynthesis? How?
13. Explain the interrelatedness of PSI and PSII in photosynthesis.
14. Researchers studied a typical hardwood forest containing a variety of trees, other plant species, fungi, and
animals. The atmospheric carbon dioxide concentrations around the forest were measured in the middle of the
day. The carbon dioxide concentration was lowest right next to the forest and steadily increased as the researchers
measured farther away from the forest.
A. Identify and describe one biological process that raises carbon dioxide concentrations by adding carbon dioxide to
the atmosphere.
B. Explain why the lowest carbon dioxide concentration occurs closest to the forest. Be sure to include a biological
process in your answer.
C. Describe how nighttime carbon dioxide concentrations near the forest should compare with the midday
concentrations near the forest. Explain your answer using two biological processes.

What process (C3 or C4) do most plants use? Why?
What is the purpose of the stoma/stomata?
What is photorespiration? What are some adaptations some plants use to combat photorespiration?
How have CAM plants evolved to reduce the rate of photorespiration?
How have C4 plants evolved to reduce the rate of photorespiration?
Where does the carbon used to build glucose in photosynthesis come from?
25. Label all parts of the following diagram.

What process is this?___________________________________
1.
Glycolysis leads to the production of ____________ and two molecules of ATP. In the absence of oxygen, fermentation leads to
the production of ______________. Glycolysis plus the citric acid cycle can convert the carbons of glucose to _________ ,
storing the energy as ATP, _____________ and ___________.
a. lactic acid, pyruvate, CO2, NADH, FADH2
b. pyruvate, lactic acid, CO2, NADH, FADH2
c. CO2, NADH, FADH2, lactic acid, pyruvate
d. O2, lactic acid, pyruvate, FADH2
e. glucose, lactic acid, CO2, NADH, FADH2
2.
In the absence of oxygen, the primary purpose of fermentation is to:
a. produce amino acids for protein synthesis
b. b.generate a proton gradient for ATP synthesis
c. oxidize (oxidize here means to combine with oxygen) glucose to generate electron carriers
d. generate alcohol for beverages
regenerate NAD+ from NADH allowing glycolysis to continue
e.
