Carbon dioxide is transported in blood mostly in which form compared to oxygen?
Answer and explanation
Correct answer: As dissolved bicarbonate
Carbon dioxide produced during cellular respiration diffuses into the blood and is transported in more than one form. Most of it is converted in red blood cells into carbonic acid and then bicarbonate ions, which travel dissolved in plasma. A smaller amount is carried as carbaminohaemoglobin or physically dissolved gas. Hence option A is correct; solid particles and fat droplets are not transport forms, and CO2 is not completely bound to haemoglobin.
