Respiration Review Questions:
Study the diagram of a mitochondrion:
1. Which molecule is represented by A?
a. glucose
b. water
c. CO2
d. chlorophyll
2. Which molecule is represented by B?
a. N2
b. Water
c. O2
d. O3
3. Cyanide is a powerful poison because it inhibits an enzyme in mitochondria, preventing
the transfer of energy during one of the steps in cellular respiration. This poison would
directly affect the production of which of the following molecules?
a. ATP
b. glucose
c. oxygen
d. RNA
4. The carbon atom in CO2 is “released” from which compound during aerobic cellular
respiration?
a. water
b. glucose
c. salt
d. chlorophyll
Study the diagram below:
5. The amount of ATP produced describes the
rate of ___________ in muscle cells.
a. photosynthesis
b. cell respiration
c. active transport
d. protein synthesis
6. As the amount of sugar is increased ATP
production..
a. increases
b. stays constant
c. decreases
d. is NOT affected
7. Which of the following conclusions is best
supported by data from this graph?
A. ATP production is independent of sugar availability.
B.
The amount of cellular respiration is constant in muscle cells.
C.
ATP is only produced when sugar concentrations are above 4 g/L.
D. The amount of cellular respiration increases as sugar concentration increases.
8 . A student created the following flowchart to summarize aerobic respiration:
Process A represents...
a. Glycolysis
b. Krebs Cycle
Process B represents...
c. Fermentation
d. Electron Transport Chain
Process C represents...
9. A cellular process that uses oxygen as one molecule of glucose is broken down to produce energy
in the form of ATP is called ______.
a. aerobic respiration b. photosynthesis
c. fermentation
d. active transport
10. Cellular respiration is the process by which cells convert the energy available in food to which
energy-rich compound?
a. water
b. CO2
c. ATP
d. DNA
11. Why do eukaryotic cells require mitochondria?
a. to package materials inside cells for transport
b. to release stored energy for cell activities
c. to control cell division for reproduction
d. to break down cell debris [wastes] for recycling
12. As respiration begins, glucose is broken down into pyruvic acid and two molecules of ATP are
formed. What will happen next in muscle cells if NO [or very little oxygen] is available?
a. photosynthesis
b. Krebs cycle
c. fermentation
d. protein synthesis

A student created the Venn Diagram below:
14.Which labeled arrow is pointing to erroneous [inaccurate] information?
a. W
b. X
c. Y
d. Z
15. SHORT RESPONSE Write in complete sentences:
Study the diagram of an experimental set up below- The class sets up an experiment with the four
flasks as shown.
Flask 1: 100 mL water, 1 mL bromthymol blue, plant
Flask 2: 100 mL water, 1 mL bromthymol blue, 2 small fish
Flask 3: 100 mL water, 1 mL bromthymol blue, 2 small fish, plant
Flask 4: 100 mL water, 1 mL bromthymol blue
BTB or Bromthymol blue
is a chemical indicator that
changes color from blue to
yellow in the presence of
CO2 [and vice versa when
levels of CO2 decrease].
All four flasks are
stoppered and placed
under the floodlight.
a.
Flask 1
Flask 2
Flask 3
Flask 4
What color would
the solution in
each flask be after
a few hours?
b. Explain how the
processes that
have occurred in
each flask result in
the observed color
of the bromthymol
blue solutions.
