Answer:
Formation of oxyhaemoglobin
Hb + 4O2 → Hb(O2)4
Breakdown of oxyhaemoglobin
Hb(O2)4 → Hb + 4O2
Step-by-step explanation:
(a) The formation of oxyhaemoglobin can be represented by the following chemical equation:
Hb + 4O2 → Hb(O2)4
In this equation, Hb represents deoxygenated haemoglobin and O2 represents oxygen. When oxygen binds to haemoglobin, oxyhaemoglobin is formed.
(b) The breakdown of oxyhaemoglobin can be represented by the following chemical equation:
Hb(O2)4 → Hb + 4O2
In this equation, Hb(O2)4 represents oxyhaemoglobin. When oxyhaemoglobin releases oxygen, it reverts back to its deoxygenated form, haemoglobin, and releases the oxygen molecules as O2
