Question

Which of the following statements about carbon dioxide transport is incorrect?

Options

Choose one · Correct answer highlighted

Most CO₂ is transported as bicarbonate ions. CO₂ binds to hemoglobin to form carbamino-hemoglobin. CO₂ transport does not affect blood pH. Correct Carbonic anhydrase facilitates CO₂ conversion into bicarbonate.

Explanation

CO₂ transport significantly affects blood pH by forming carbonic acid, which dissociates into bicarbonate and hydrogen ions.
