When trying to determine the rate of cellular respiration (an aerobic process), why is oxygen measured and not carbon dioxide
dusya [7]

Since both aerobic and anaerobic processes can result in the production of CO2, we couldn't be certain that cellular respiration was occurring.

Carbon dioxide:

Carbon dioxide is released during cellular respiration as a waste product. Cells that are capable of photosynthesis can utilize this carbon dioxide to create new carbohydrates. Additionally, oxygen gas is necessary to act as an electron acceptor during the process of cellular respiration.

There are two types of cellular respiration: aerobic (occurring when oxygen is present) and anaerobic (in absence of oxygen).

Now, carbon dioxide is emitted as a byproduct in both types of respiration.

Therefore, determining the rate of aerobic cellular respiration by measuring the amount of carbon dioxide emitted is impossible.

Therefore, to obtain the precise rate, we monitor oxygen rather than carbon dioxide.

Therefore, the correct response is that CO2 is created during both aerobic and anaerobic processes; we were unable to confirm if cellular respiration was occurring.
