A) Partial pressure of \[C{{O}_{2}}\] can interfere with \[{{O}_{2}}\]binding with haemoglobin
B) Higher \[{{H}^{+}}\]conc. in alveoli favours the formation of oxyhaemoglobin
C) Low \[pC{{O}_{2}}\] in alveoli favours the formation of oxyhaemoglobin
D) Binding of oxygen with haemoglobin is mainly related to partial pressure of \[{{O}_{2}}\]
Correct Answer: B
Solution :
| [B] The correct option is [b] because higher \[{{H}^{+}}\] concentration favours the dissociation of oxygen from oxyhaemoglobin in tissues. In the alveoli, high \[p{{O}_{2}}\], low \[pC{{O}_{2}}\], lesser \[{{H}^{+}}\] concentration and lower temperature favour formation of oxyhaemoglobin. |
