The graph illustrates how three different partial pressures of carbon dioxide affect the oxygen dissociation curve of human haemoglobin. How does a lower partial pressure of carbon dioxide affect haemoglobin?
- AIt is less efficient at taking up oxygen and less efficient at releasing oxygen.
- BIt is less efficient at taking up oxygen and more efficient at releasing oxygen.
- CIt is more efficient at taking up oxygen and less efficient at releasing oxygen.
- DIt is more efficient at taking up oxygen and more efficient at releasing oxygen.
