What has the primary responsibility for sensing and responding to changes in blood levels of CO₂?

Question

Quizplus · Accepted Answer

Hydrogen ions stimulate highly responsive chemosensitive nerve cells, located bilaterally in the medulla. Nevertheless, these central chemoreceptors are extremely sensitive to CO₂ in an indirect fashion. Through the hydrolysis reaction, as CO₂ increases there is a greater release of hydrogen ions to which the chemoreceptors respond.
