Current Question (ID: 14415)

Question:

Choose the incorrect statement

Options:

1. Every 100 ml of deoxygenated blood delivers approximately 4 ml of CO₂ to the alveoli
2. Carbonic anhydrase is present in very high concentration in RBC
3. High pCO₂ and low pO₂ in tissues help in binding of carbon dioxide
4. CO₂ is carried in haemoglobin as carboxyhaemoglobin

Solution:

CO₂ is mainly transported in the blood in three forms: as bicarbonate ion (HCO₃⁻) in the plasma (about 70% to 80%), dissolved in the plasma (about 7% to 10%), and bound to hemoglobin as carbaminohemoglobin (about 20%). Carboxyhemoglobin is formed when carbon monoxide (CO) binds to hemoglobin instead of oxygen, which can be harmful as it prevents oxygen from binding to hemoglobin.
