Increased carbon dioxide in the blood increases respiration (breathing) rate. Which of these statements would apply to this mechanism?

Question

Quizplus · Accepted Answer

Increased carbon dioxide triggers an increase in respiration rate in order to decrease carbon dioxide levels in the blood, which is a return to normal levels. This negative feedback mechanism is a common regulatory process in the body, keeping levels of substances within a narrow range for optimal function. Option A is incorrect because this is not a rare example, as negative feedback is the most common feedback mechanism in the body. Option B is incorrect because it refers to a different mechanism involving oxygen levels, not carbon dioxide levels. Option D is incorrect because it does not accurately describe negative feedback, which is the opposite of "enhanced and made larger" deviation from normal levels. Option E is partially correct, but the second part of the statement is redundant and unnecessary.
