Read the following statements and find out the incorrect statement(s). a. The binding of CO2 with haemoglobin is related to the partial pressure of CO2-pO2 is a major factor which could affect this binding. b. When pCO2 is low and pO2 is high as in the alveoli, more binding of CO2 occurs, whereas when the pCO2 is high and pO2 is low as in the tissues, dissolution of CO2 from carbamino-haemoglobin takes place. c. At the tissue site, where partial pressure of CO2 is high due to catabolism, CO2 diffuses into blood (RBCs and plasma) and forms HCO3- and H+. At the alveolar site where pCO2 is low, the reaction proceeds in the opposite direction leading to the fomiation of CO2 and H2O. d. Oxygen dissociation curve is highly useful in studying the effect of factor like pCO2, H+ concentration, etc., on binding of O2 with haemoglobin.

When pCO2 is high and pO2 is low as in the alveoli, more binding of O2 occurs, whereas when the pCO2 is high and pO2 is low as in the tissues, dissociation of O 2 from oxyhaemoglobin takes place

When pCO2​ is high and pO2​ is low as in the alveoli, more binding of O2​ occurs, whereas when the pCO2​ is high and pO2​ is low as in the tissues, dissociation of O2​ from oxyhaemoglobin takes place

When $pC O_{2}$ is high and $p O_{2}$ is low as in the alveoli, more binding of $O_{2}$ occurs, whereas when the $pC O_{2}$ is high and $p O_{2}$ is low as in the tissues, dissociation of $O_{2}$ from oxyhaemoglobin takes place
