The results for oxygen and carbon dioxide in the samples of breathed-out air taken before and after exercise are different. Describe and explain these differences. - AnsIn breathed-out air, after exercise there is less oxygen and more carbon dioxide. As a higher amount of energy is required during exercise for muscle contractions. The muscle cell's respire at a faster rate. Therefore, rate of gas exchange increases. Hence, more oxygen is absorbed into the blood and more carbon dioxide i...
