Example Questions

Example Question #1 : Cellular Respiration

All of following are true of cellular respiration EXCEPT __________.

Possible Answers:

cellular respiration is an anaerobic process

oxygen is the final electron acceptor

cellular respiration takes place in the mitochondrion

cellular respiration is the most efficient way to harvest energy from glucose

cellular respiration yields 36–38 ATP

Correct answer:

cellular respiration is an anaerobic process

Explanation:

Cellular respiration is NOT an anaerobic process. It is exactly the opposite! Cellular respiration uses oxygen as its final electron acceptor making it an aerobic process. Anaerobic process do not use oxygen. 

Example Question #2 : Cellular Respiration

For each molecule of glucose, how many ATP are produced by the Citric Acid Cycle? 

Possible Answers:

3 ATP

2 ATP

1 ATP

4 ATP

6 ATP

Correct answer:

2 ATP

Explanation:

Each molecule of glucose produces 2 pyruvate molecules. Each of these pyruvate molecules go through the citric acid cycle and produce 1 ATP each, resulting in 2 ATP total.

Example Question #3 : Cellular Respiration

How many ATP molecules are produced per glucose molecule in anaerobic respiration?

Possible Answers:

Correct answer:

Explanation:

Anaerobic respiration takes place when oxygen is low, such as when lactic acid fermentation takes place in human muscle tissue. This can be painful and cause some of the cramps experienced during intense exercise. Anaerobic respiration is much less efficient at producing ATP than aerobic respiration; it only produces 2 ATP per glucose molecule vs. 36 net ATP in aerobic respiration.
