Identify the wrong statement with reference to transport of oxygen.

1. Partial pressure of CO2 can interfere with O2 binding with haemoglobin
2. Higher H+ conc. in alveoli favours the formation of oxyhaemoglobin
3. Low pCO2 in alveoli favours the formation of oxyhaemoglobin
4. Binding of oxygen with haemoglobin is mainly related to partial pressure of O2

Correct answer: Higher H+ conc. in alveoli favours the formation of oxyhaemoglobin

Solution

The wrong statement is the one claiming higher H+ in alveoli favors oxyhaemoglobin formation. In reality, increased H+ lowers hemoglobin’s affinity for oxygen and promotes dissociation, while low CO2 and high pO2 in alveoli favor oxygen loading.
