Question

The combination of oxygen with haemoglobin is called as

• A. Oxidation
• B. Oxyhaemoglobin
• C. Reduction
• D. None of the above

Answer 1

The correct option is B Oxyhaemoglobin

Oxygenation literally means the addition of oxygen to a chemical substance or physical system. Thus binding of oxygen with haemoglobin can also be reffered as oxygenation. Oxyhemoglobin is formed when oxygen binds to the heme component of the protein hemoglobin in red blood cells, during physiological respiration.
Whereas oxidation is a loss of electron, which can be either in the form of gaining of oxygen or loss of hydrogen and reduction is a gain of electron, which can be either in the form of loss of oxygen or gaining of hydrogen.
