Question

Quizplus · Accepted Answer

Haemoglobin can bind with oxygen (O2), carbon dioxide (CO2), hydrogen ions (H+), nitric oxide (NO), and carbon monoxide (CO). It is the ability of haemoglobin to bind with these gases that makes it an important transport molecule in the body. Option A is incorrect because haemoglobin is found in the cytoplasm of red blood cells, not in the nucleus. Option B is incorrect because carbonic anhydrase is an enzyme found in red blood cells but not in haemoglobin. Option D is incorrect because haemoglobin can also bind with CO2, H+, NO, and CO, not just O2.
