Select the favourable conditions required for the formation of oxyhaemoglobin at the alveoli. (1) High pO2 , low pCO2 , less H+, lower temperature (2) Low pO2 , high pCO2 , more H+, higher temperature (3) High pO2 , high pCO2 , less H+, higher temperature (4) Low pO2 , low pCO2 , more H+, higher temperature
Option 1) High pO2, low pCO2, lesser H+concentration and lower temperature are all favourable factors for the formation of oxyhaemoglobin at the alveoli.
