and
Cellular Respiration
“The difference between school and life? In school, you're taught a lesson and
then given a test. In life, you're given a test that teaches you a lesson.”

"If more testing were the answer to the problems in our schools, testing would have
solved them a long time ago.“

Name ___________________________________________ Date ________________ Period __________
Directions: This test is designed to let your teacher know how much information you have learned
over the past few weeks, and to allow you to gauge this as well. Remember to think about your notes, and
all the examples and demonstrations that we’ve done in class. Read each question carefully and completely
before making your response, and make sure that whatever you write answers every part of the question. Do
not leave any blank questions or naked numbers. Blank questions will be marked off at double the rate of a
wrong answer. Relax, good luck, and enjoy!
0. What is the worst thing to have happen at 6:00 a.m.?
1. What is the purpose of the mitochondrion?
A. To create polypeptides.
B. To make energy for the cell.
C. To make proteins.
D. To hook amino acids together.
_________
2. What is the function of the spindle apparatus in mitosis?
3. The levels of organization for structure and function in the human body from least complex to most
complex are
A. systems → organs → tissues → cells
B. cells → organs → tissues → systems
C. tissues → systems → cells → organs
D. cells → tissues → organs → systems
_________
4. Which process would produce a species with very little genetic variation?
A. Sexual reproduction
B. Acrosomal Strategery
C. Asexual reproduction
D. Pinocytosis
_________
5. A beaker is divided by a membrane as shown below. The membrane is permeable to water, but not to
glucose. Draw the appearance of the beaker after several minutes.
glucose
6. A student observes that paramecia, when viewed under a microscope, move very rapidly. In order to
continue their motion, they must have a lot of energy. The organelle most directly associated with producing
this energy is the
A. E.R.
B. Mitochondrion
C. Nucleus
D. Chloroplast
_________
7. The best way to classify organisms is by
A. Grouping by color
B. Size
C. Their DNA
C. Type of eye
_________
8. Which process usually uses carbon dioxide molecules?
A. cellular respiration B. asexual reproduction C. active transport D. autotrophic nutrition
_________
9. When would a cell use fermentation?
10. Marine sponges contain a biological catalyst that blocks a certain step in the separation of chromosomes.
Which stage in mitosis would be directly affected by this catalyst?
A. Interphase
B. Prophase
C. Metaphase
D. Anaphase
_________
11. Eukaryotes are cells which have nuclei, while prokaryotes do not. Give one example of each type of
cell.
12. The picture to starboard represents a mitochondrion performing a life process. What do the arrows
represent?
A. Electrophoresis
C. ADP usage
B. Release of carbon dioxide
D. Intake of calcium
_________
Use the diagram to the left to answer questions 13 and 14.
13. What process is represented in the diagram above?
A. Krebs cycle
B. Cellular respiration
C. Glycolysis
D. E.T.C
14. What is the main product of the process above, and where does it go after it is produced?
_________
15. Which part of cellular respiration creates the most ATP?
A. Krebs cycle
B. Glycolysis
C. Reduction
D. Electron Transport Chain
_________
16. What is the function of NADH and FADH2 in cellular respiration?
A. They help add phosphates to molecules to give them more energy.
B. They move oxygen to the end of the E.T.C. so that it can be the final electron acceptor.
C. They carry electrons from glycolysis and Krebs to the E.T.C.
D. They act as tugboats to move glucose through cellular respiration.
_________
17. Why do we exhale carbon dioxide?
A. It is produced in glycolysis
B. It is not needed by the body, so it is simply not absorbed in the lungs
C. Three molecules per pyruvate are produced in the Krebs cycle.
D. Both B and C.
_________
18. What is the purpose of fermentation?
19. What is the final electron acceptor in cellular respiration?
20. What is the purpose of “investing” two ATPs at the beginning of glycolysis?
21. Why must oxaloacetate be regenerated in the Krebs cycle?
A. If it wasn’t, there would be nothing to add Acetyl CoA to, and the cycle would stop.
B. They cycle would stop because no ATP would be delivered by NADH.
C. The cycle would continue, using fermentation instead.
D. The E.T.C. needs oxaloacetate as the final electron acceptor, so it would stop.
_________
22. When a molecule is oxidized, it
A. Looses a neutron B. Gains a neutron
_________
C. Looses an electron
D. Gains an electron
23. On the diagram of a mitochondrion below, indicate where protons are stored, and show how they move
to create ATP.
Use the cladogram to starboard to answer questions 24 and 25.
24. Which two groups are most closely related?
25. Which species are extant?
26. Put a check next to the correct location of the following processes.
Cytoplasm
Mitochondrion
Chloroplast
Glycolysis
Krebs Cycle
Electron Transport Chain
27. What is the overall purpose of cellular respiration?
28. What are two important things that happen during interphase?
29. Why would a cell have to use fermentation?
A. There is too much carbon dioxide
B. No oxygen is present
C. To avoid ATP loss from over-phosphorylation D. Not enough proteins in the E.T.C.
_________
30. Why do cells make chromatin into chromosomes during mitosis?
31. The steps of mitosis are much like a well-choreographed dance; they must go in just the right order, or
the whole thing falls apart. Most of the time, mitosis goes very smoothly. However, mistakes can be made.
One such mistake has been recently reported in a paper from 2005. The scientists who discovered the
mistake found that in some cells, instead of just two centrosomes (one at each side of the cell), there are
sometimes three or more.
In a few, well-organized paragraphs, completely explain what would happen to the resulting daughter
cells and what would be different about anaphase and telophase if more than two centrosomes existed. If
you wish, you may draw a picture to help explain your answer, but you must have a written response as well.
