Ch. 3.5 Cellular Respiration and Energy Transformations
Partial Test Review
Remember to study your Open Journal Quiz!!!
1. What are the three parts/steps/stages of aerobic respiration in order?
Glycolysis, Krebs Cycle, Electron Transport Chain
2. What are the reactants for the equation for cellular respiration?
Glucose and 6 O2 molecules
3. What process is used to make beer and wine?
Alcoholic fermentation
4. How many ATPs are produced by cellular respiration (if oxygen is
present)?
36
5. Why do we breathe heavily after running a race?
To re-oxygenate our cells. The more energy you need, the more oxygen you
need.
6. What is a process that does not release energy from glucose?
Photosynthesis
7. Air is filtered, warmed and moistened where in our body?
Mouth/nose
8. What structure forces air into the lungs when it contracts?
Diaphragm
9. How is aerobic and anaerobic respiration similar? How are they different?
Similar- they both use glucose in glycolysis to make ATP.
Different- they make different amounts of ATP (aerobic=32, anaerobic=2).
Aerobic uses oxygen while anaerobic does not.
10. Where does aerobic respiration occur in the cell? Where does anaerobic
respiration occur?
Aerobic- starts in the cytoplasm, then it creates energy in the mitochondria.
Anearobic happens in the cytoplasm only, since it is just glycolysis and lactic acid
production.
11. Write the balanced equation for cellular respiration.
C6H12O6 + 6O2 6CO2 + 6H2O + 36 ATP
12. How is cellular respiration similar to photosynthesis? How is cellular
respiration different from photosynthesis?
It is essentially the reverse reaction, all compounds are the same. However,
photosynthesis gets it’s energy from sunlight and cellular respiration makes
energy that is stored in ATP.
13. Where do you label the independent variable in a graph?
On the X-axis.
14. Where do you label the dependent variable in a graph?
On the Y-axis

16. What does the respiratory system have to do with cellular respiration?
It is the reason oxygen enters the body so that it can travel to all of the cells.
Without oxygen, we wouldn’t be able to create the energy we need to live.
