An increase in carbon dioxide in human blood causes the oxyhaemoglobin dissociation curve to move to the right. What explains this effect?
- AAn increase in carbon dioxide concentration increases the ventilation rate.
- BCarbon dioxide is more soluble than oxygen and displaces it.
- CDiffusion of carbon dioxide between the alveoli and the blood is more rapid.
- DIncreasing the H$^+$ concentration decreases haemoglobin affinity for oxygen.
