Which of the following statements regarding the transport of CO2 is no

1.	Which of the following statements regarding the transport of CO2 is not true?(a) CO2 is carried by haemoglobin as carbaminohaemoglobin(b) pCO2 is high and pO2 is low in the tissues(c) In the tissues, pCO2 is high and it diffuses into blood and forms CO2 and HO2(d) Every 100 mL of deoxygenated blood delivers approximately 4 mL of CO2 to the alveoli
Answer» Answer is : (c) In the tissues, pCO₂ is high and it diffuses into blood and forms CO₂ and H₂O The statement (c) is incorrect. CO₂ is trapped as bicarbonates at the tissue site and is transported to the alveoli where it is released out as CO₂. Carbon dioxide is immediately converted into H₂CO₃ after entering into the blood. This H₂CO₃ forms bicarbonates. transport of h2o is not true
