Remember the law of conservation of mass. The human body uses cellular respiration to make energy.
Using the chemical equation for cellular respiration, explain how the amounts of oxygen and carbon dioxide inhaled by the lungs is different from the amounts exhaled. Explain your answer in 1-2 sentences.
1 answer
The amounts of oxygen inhaled and carbon dioxide exhaled are different because during cellular respiration, oxygen is consumed and converted into carbon dioxide as a byproduct, which is then released through exhalation.
