Multiple Choice
Which of the following is true of aerobic respiration compared to anaerobic respiration?
A
Aerobic respiration does not require oxygen, whereas anaerobic respiration does.
B
Aerobic respiration results in the production of lactic acid, while anaerobic respiration produces carbon dioxide and water.
C
Aerobic respiration occurs in the cytoplasm, while anaerobic respiration occurs in the mitochondria.
D
Aerobic respiration produces more ATP per glucose molecule than anaerobic respiration.
Verified step by step guidance1
Understand the basic definitions: Aerobic respiration requires oxygen and occurs in the mitochondria, while anaerobic respiration does not require oxygen and occurs in the cytoplasm.
Identify the main products of each type of respiration: Aerobic respiration produces carbon dioxide, water, and a large amount of ATP, whereas anaerobic respiration typically results in lactic acid (in animals) or ethanol and carbon dioxide (in yeast and plants) with a smaller yield of ATP.
Compare the ATP yield: Aerobic respiration is more efficient in terms of energy production, generating approximately 36-38 ATP molecules per glucose molecule, compared to anaerobic respiration, which produces only about 2 ATP molecules per glucose.
Recognize the conditions under which each type of respiration occurs: Aerobic respiration occurs when oxygen is available, while anaerobic respiration takes place in environments lacking oxygen or during intense exercise when oxygen supply is insufficient.
Conclude with the correct statement: Aerobic respiration produces more ATP per glucose molecule than anaerobic respiration, making it the more efficient process for energy production.
