Answer :
Final answer:
Anaerobic metabolism increases the production and exhalation of carbon dioxide. While cardiopulmonary arrest and increased cardiac output could cause an indirect increase, excessive ventilation typically decreases exhaled CO2.
Therefore, option C is correct.
Explanation:
The factors mentioned in the question could all have some impact on the amount of exhaled carbon dioxide, but the one that could specifically cause an increase is c) anaerobic metabolism. This is because anaerobic metabolism, or the process of producing energy without the presence of oxygen, results in the production of carbon dioxide as a byproduct. Cardiopulmonary arrest and increased cardiac output could indirectly cause more carbon dioxide to be produced and exhaled, if they result in more anaerobic metabolism in the body.
It's also worth noting that excessive ventilation will tend to decrease rather than increase exhaled CO2, as it could lead to respiratory alkalosis, a condition where there is too little CO2 in the blood.
