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 does not prevent muscle fatigue; in fact, it can contribute to it (e.g., lactic acid build - up in muscles).
• Anaerobic respiration (glycolysis followed by fermentation) generates a low yield of ATP compared to aerobic respiration.
• In the production of beer (yeast fermentation), wine (yeast fermentation), bread (yeast fermentation - CO₂ production causes rising), yogurt (lactic acid fermentation by bacteria), and cheese (lactic acid fermentation by bacteria), anaerobic respiration (fermentation) is used.
• Animals cannot rely on anaerobic respiration for several days. Anaerobic pathways (like lactic acid fermentation in animals) are short - term energy - providing mechanisms.

Answer:

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