What does the Oxygen dissociation curve represent?

What does the Oxygen dissociation curve represent?
  1. The relationship between the saturation of haemoglobin with CO₂ and pCO₂
  2. The relationship between the saturation of haemoglobin with O₂ and pO₂
  3. The relationship between the saturation of haemoglobin with H⁺ concentration and pO₂
  4. The relationship between the saturation of haemoglobin with temperature and pO₂

Solution

The Oxygen dissociation curve represents the relationship between the saturation of haemoglobin with O₂ and the partial pressure of O₂ (pO₂).
