B. Cellular respiration uses oxygen
B. Cellular respiration uses oxygen and C. Cellular respiration produces carbon dioxide
Yes, both B. Cellular respiration uses oxygen and C. Cellular respiration produces carbon dioxide can be concluded from the data in the table. The percentage of oxygen in inhaled air is higher than in exhaled air, indicating that oxygen is being used during cellular respiration. The percentage of carbon dioxide in exhaled air is higher than in inhaled air, indicating that carbon dioxide is being produced during cellular respiration.
