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

Options

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

Answer

D

Explanation

• High `pO_(2)` , low `pCO_(2)` , lesser `H^(+)` concentration and lower temperature are all favourable factors for the formation of oxyhaemoglobin at the alveoli.
• The favourable conditions for the dissociation of oxygen from oxyhaemoglobin at the tissue level are, low `pO_(2)` , high `pCO_(2)` , high `H^(+)` concentration and high temperature.
