Question: Answer the following question given this paragraph: In summary, aerobic and anaerobic respiration each have advantages under specific conditions. Aerobic respiration produces far more ATP, but risks exposure to oxygen toxicity. Anaerobic respiration is less energy-efficient, but allows survival in habitats which lack oxygen. Within the human body, both are important to muscle function. Muscle cells specialized for aerobic respiration provide endurance, and those specialized for lactic acid fermentation support short but intense energy expenditures. Both ways of making ATP play critical roles in life on earth. Q: What exposure risk comes with aerobic respiration? Choices: - helium toxicity - carbon toxicity - nitrogen toxicity - oxygen toxicity A:
Answer: oxygen toxicity
