What are the major transport mechanisms for CO2? Explain
About 20 – 25% of CO2 is transported by the red blood cells as carbaminohaemoglobin. Carbon dioxide binds to the amino groups on the polypeptide chains of haemoglobin and forms a compound known as carbaminohaemoglobin. (3) Through sodium bicarbonate: About 70% of carbon dioxide is transported as sodium bicarbonate.
