Detailed explanation-1: -Best Answer. Explanation: The correct chemical formula of oxyhaemoglobin is Hb (O2 )4 which is diamagnetic yet the lowest-energy electron configuration. Oxyhemoglobin is hemoglobin that binds to oxygen, and oxygen is carried in this form to the tissues of the lungs.

Detailed explanation-2: -Hb + 4O2 → Hb(O2)4. One haemoglobin molecule carries four oxygen molecules. About 98.5% of the oxygen in blood is transported as oxyhaemoglobin. In the lower concentrations of oxygen found in respiring tissues, the oxyhaemoglobin dissociates to release oxygen.

Detailed explanation-3: -Oxyhaemoglobin is formed in the lungs when oxygen binds to haemoglobin, present in the RBCs. Oxygen binds to the haemoglobin reversibly. Haemoglobin is the respiratory pigment present in RBCs. It is required for the transport of oxygen from the lungs to various tissues.

Detailed explanation-4: -When oxygen is associated with the molecule it is termed oxyhemoglobin (OHb), whilst in the absence of oxygen it is termed deoxyhemoglobin or reduced hemoglobin (RHb). In these forms iron is present as iron(II).

Detailed explanation-5: -Oxyhemoglobin is the normal, oxygen-carrying form of hemoglobin in which iron is in the reduced (ferrous) state. Methemoglobin is a nonfunctional form of hemoglobin in which ferrous iron is oxidized to ferric iron. Methemoglobin is nonfunctional because it cannot bind oxygen.
