Question

which statement about anaerobic respiration is true?
anaerobic respiration prevents muscle fatigue.
anaerobic respiration generates a high yield of atp.
anaerobic respiration is used commercially in the production of beer, wine, bread, yogurt, and cheese.
anaerobic respiration can provide energy to animals for several days in the absence of oxygen.

Explanation:

• Anaerobic respiration in animals (like lactic acid fermentation in muscle cells) actually causes muscle fatigue (so the first option is wrong).
• Anaerobic respiration (such as fermentation) generates a low yield of ATP compared to aerobic respiration (so the second option is wrong).
• In the production of beer (yeast fermentation), wine (yeast fermentation), bread (yeast fermentation - CO₂ makes it rise), yogurt (lactic acid bacteria fermentation), and cheese (bacterial fermentation), anaerobic respiration (fermentation) is used.
• Anaerobic respiration in animals (e.g., lactic acid fermentation) can only provide energy for a short - term (minutes) in the absence of oxygen, not several days (so the fourth option is wrong).

Answer:

Anaerobic respiration is used commercially in the production of beer, wine, bread, yogurt, and cheese.
