Answer and explanation
Correct answer: B. It binds oxygen in the lungs, where the partial pressure is high, and releases it in respiring tissues
- Step 1: Haemoglobin has a high affinity for oxygen at high partial pressure. Step 2. It unloads where the pressure is low. Answer: it carries oxygen. Why not the others: these are other proteins or functions.
