Example Questions
Example Question #1 : Cellular Respiration
All of following are true of cellular respiration EXCEPT __________.
oxygen is the final electron acceptor
cellular respiration is an anaerobic process
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
cellular respiration is an anaerobic process
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?
2 ATP
1 ATP
6 ATP
4 ATP
3 ATP
2 ATP
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 #1 : Cellular Respiration
How many ATP molecules are produced per glucose molecule in anaerobic respiration?
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.
