Select the favourable conditions required for the formation of oxyhaemoglobin at the alveoli.
Options
- AHigh p O 2 , low p C O 2 , less H + , lower temperature
- BLow p O 2 , high p C O 2 , more H + , higher temperature
- CHigh p O 2 , high p C O 2 , less H + , higher temperature
- DLow p O 2 , low p C O 2 , more H + , higher temperature
Correct answer
A. High p O 2 , low p C O 2 , less H + , lower temperature
Step-by-step solution
In the alveoli, where there is high pO 2 , low pCO 2 , lesser H + concentration, and lower temperature, the factors are all favourable for the formation of oxxhaemoglobin, whereas, in the tissues, where low pO 2 , high pCO 2 , high H + concentration and higher temperature exist, the conditions are favourable for dissociation of oxygen from the oxyhaemoglobin.
