प्रश्न
What is the effect of pCO2 on oxygen transport?
उत्तर
- pCO2 plays an important role in the transportation of oxygen. At the alveolus, the low pCO2 and high pO2 favour the formation of haemoglobin.
- At the tissues, high pCO2 and low pO2 favour the dissociation of oxygen from haemoglobin. Hence, the affinity of haemoglobin for oxygen is enhanced by the decrease of pCO2 in the blood.
- Therefore, oxygen is transported in blood as oxyhaemoglobin and oxygen dissociates from it at the tissues.
