   Select the favourable conditions required for the formation of oxyhaemoglobin at the alveoli.
   A Low $pO_2$, high $pCO_2$, more $H^+$, higher temperature

   B High $pO_2$, high $pCO_2$, less $H^+$, higher temperature

   C Low $pO_2$, low $pCO_2$, more $H^+$, higher temperature

   D High $pO_2$, low $pCO_2$, less $H^+$, lower temperature

   Identify the wrong statement with reference to transport of oxygen.
   A Partial pressure of $CO_2$ can interfere with $O_2$ binding with haemoglobin.

   B Higher $H^+$ conc. in alveoli favours the formation of oxyhaemoglobin.

   C Low $pCO_2$ in alveoli favours the formation of oxyhaemoglobin.

   D Binding of oxygen with haemoglobin is mainly related to partial pressure of $O_2$.
