Question

Explain why air exhaled during exercise contains more carbon dioxide than exhaled at rest​

Answer 1

Answer:

In addition, the blood contains some carbon dioxide (a waste product) that is transferred to the air in the lungs, which is then exhaled. The result is that the exhaled air contains less oxygen and more carbon dioxide than the inhaled air.

Answer 2

You will exhale more CO₂ during exercise because the body consumes more glucose and oxygen during exercise than when at rest.

During exercise the body require a lot of energy than usual hence more calories( glucose ) are burnt with oxygen to provide such energy therefore releasing more CO₂ as waste product , therefore you will exhale more CO₂  while exercising.

Hence we conclude that it is because the body consumes more glucose and oxygen during exercise than at rest.
