Question

Identify the wrong statement with reference to transport of oxygen.

• A. Low H${}^{+}$ concentration in alveoli favours the formation of oxyhaemoglobin
• B. Formation of oxyhaemoglobin is mainly related to partial pressure of CO${}_2$
• C. High pCO${}_2$ in tissues favours the dissociation of oxyhaemoglobin
• D. High pO${}_2$ in alveoli favours the formation of oxyhaemoglobin

Answer 1

The correct option is B Formation of oxyhaemoglobin is mainly related to partial pressure of CO${}_2$

Formation of oxyhaemoglobin is mainly related to partial pressure of O${}_2$. Binding of haemoglobin with O${}_2$ increases by high pO${}_2$, low pCO${}_2$, low temperature and low H${}^{+}$ at alveolar level.
