Question
How many of the given statements are wrong?
A. The rate of diffusion of gas at the respiratory membrane depends upon its solubility as well as on the thickness of membrane.
B. The amount of CO2 that can diffuse through the diffusion membrane per unit difference in partial pressure is much higher when compared to that of O2.
C. Oxygen can bind with haemoglobin in an irreversible manner to form oxyhaemoglobin.
D. The factors responsible for formation of oxyhaemoglobin include high pO2, low pCO2,high H+ concentration and low temperature.

Solution
The correct option is B Two
O2 binds with haemoglobin in a reversible manner . In the alveoli, where there is high pO2, low pCO2, lesser H+ concentration and lower temperature, the factors are all favourable for the formation of oxyhaemoglobin.
