- Q11A student measured the oxygen and carbon dioxide composition of exhaled air during exercise. What differences would you see in the composition of exhaled air at rest compared to exhaled air during exercise?The oxygen concentration would be the same and the carbon dioxide concentration lower at rest.There would be a greater carbon dioxide concentration and lower oxygen concentration at rest.There would be a greater oxygen concentration and lower carbon dioxide concentration at rest.The carbon dioxide concentration would be the same and the oxygen concentration higher at rest.30s4.1.3.1
