Quizplus · Accepted Answer

The increase in carbon dioxide levels will stimulate the brain to increase the breathing rate in order to eliminate the excess CO2 through exhalation. This is known as the respiratory drive. The decrease in pH may also stimulate the respiratory drive, but it is primarily the increase in CO2 levels that initiates this response.
