Select the favourable conditions required for the formation of oxyhaemoglobin at the alveoli.

Options

  1. AHigh p O 2 , low p C O 2 , less H + , lower temperature
  2. BLow p O 2 , high p C O 2 , more H + , higher temperature
  3. CHigh p O 2 , high p C O 2 , less H + , higher temperature
  4. 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.
