Question

Choose the correct statement

• A. A Hemoglobin molecule can carry three molecules of oxygen
• B. RBCs contain a very low concentration of carbonic anhydrase
• C. Low pO2 and high pCO2 in the tissues are favourable for the formation of oxyhemoglobin
• D. The solubility of CO2 is higher than that of O2

Answer 1

Answer:

D. The solubility of CO2 is higher than that of O2

• The solubility of CO2 is higher than that of O2.

• This statement is correct because carbon dioxide (CO2) is more soluble in blood than oxygen (O2).

The other options are incorrect:

1. A Hemoglobin molecule can carry four molecules of oxygen, not three.

2. RBCs actually contain a high concentration of carbonic anhydrase.

3. Low pO2 and high pCO2 in the tissues favor the release of oxygen from hemoglobin, not the formation of oxyhemoglobin.
