Study Guide Unit Two: Cell Respiration
Vocabulary: Use your notes to find the following definitions. A word bank is provided.
1. ____________________________- A molecule that stores energy in phosphate bond, used to
power cells.
2. ____________________________ - Organisms that use light energy from the sun to produce
food
3. ____________________________ - Organisms that get their energy from eating other organisms
4. ____________________________- Oxygen and NADH enters this cycle, you get 32 ATP, water
coming out
5. ____________________________- Type of respiration that occurs in the presence of oxygen
6. ____________________________-Cycle in which pyruvate is converted into CO2; 2ATP and
NADH.
7. ____________________________-Enzyme used in the production of ATP
8. ____________________________ – The organelle where cellular respiration takes place
9. ____________________________ – A type of anaerobic respiration that occurs in muscle cells
when oxygen is low
10. ____________________________– A type of anaerobic respiration that occurs in bacteria and
yeast, which produces ethanol as a byproduct.
11. ____________________________-A measurement of how much energy is in your food
12. ____________________________- Type of respiration that occurs when there is no oxygen
13. ____________________________- A protein that speeds up biological reactions without being
used up on the process
14. ____________________________-Cycle in which glucose enters and 2 ATP, pyruvate (pyruvic
acid), and NADH are produced
15. ____________________________– The ultimate source of energy for ALL living things.
16. ____________________________- A sugar, food is broken down into this to be used by the body
17. ____________________________-The location of the Krebs cycle
18. ____________________________-The location of the electron transport chain
19. ____________________________- A molecule produced by both glycolysis and the krebs cycle,
used in the electron transport chain.
20. ____________________________- A gas that is a product of the Krebs cycle and of fermentation
21. ____________________________- A molecule that is produced by glycolysis and used in the
Krebs cycle

Short Answer
1. List the three steps involved in Cellular Respiration and give the amounts of ATP
produced in each.
2. What is the difference between Aerobic respiration and Anaerobic respiration?
3. Who uses Cellular Respiration?
4. Using the picture below label the structure of the mitochondria.
A.
C.
B.
5. Describe the relationship between activation energy and enzymes (A graph may help
you).
6. (Why do you need to breathe? Where is oxygen used in your body (location and
process). Include something about ATP in your answer….
7. Describe the role of enzymes in our laundry detergent lab. Why did you make a
protein substrate? Why did your substrate turn into a liquid?
8. What type of fermentation did we produce with our yeast lab and what type of gas was
released in the process? How much ATP was created per glucose molecule during
this process?
9. What are the products and reactants of the Krebs cycle?
10. What are the products and reactants of Glycolysis?
11. What are the products and reactants of Electron Transport Chain?
12. Review your packet and notes.
