Cellular Respiration
- 1.
Which equation below best represents cellular respiration?
- A.
H2O + CO2 → C6H12O6 + H2O
- B.
O2 + C6H12O6 → H2O + CO2
- C.
H2O + CO2 → C6H12O6 + O2
- D.
H2O + O2 → C6H12O6 + CO2
Correct Answer
B. O2 + C6H12O6 → H2O + CO2Explanation
Cellular respiration is the process where glucose is turned into ATP energy by using oxygen to break down glucose into H20 and CO2.Rate this question:

What do glycolysis, fermentation and cellular respiration all have in common?
- A.
All require oxygen to break molecular bonds for ATP production
- B.
All processes occur in all living organisms.
- C.
All are metabolic pathways by which cells obtain or use energy.
- D.
All produce relatively equal amounts of ATP.
Correct Answer
C. All are metabolic pathways by which cells obtain or use energy.Explanation
All are examples of ways that organisms obtain energy through metabolism. All do NOT require oxygen, do NOT occur in all living organisms, and do NOT produce equal amounts of ATP.Rate this question:

Which of the following is used in anaerobic respiration?
- A.
Oxygen
- B.
Cytoplasm
- C.
Mitochondria
- D.
Sunlight
Correct Answer
B. CytoplasmExplanation
Anaerobic means without oxygen. The process of glycolysis occurs in the cytoplasm of the cell and does NOT require, oxygen, mitochondria or sunlight.Rate this question:

Select the reactants of cellular respiration.
- A.
H20
- B.
CO2
- C.
C6H12O6
- D.
O2
- E.
2 molecules of ATP
Correct Answer(s)
C. C6H12O6
D. O2
E. 2 molecules of ATPExplanation
In order for respiration to occur, glucose is broken down using 2 molecules of ATP in the cytoplasm. Oxygen is necessary for the reaction that occurs in the mitochondria.Rate this question:
