Explanation of the Role of Oxyhaemoglobin



  • Neutral: Oxyhaemoglobin is considered neutral because it has no effect on the pH of the blood.

  • Buffer: Oxyhaemoglobin can act as a buffer in the blood to help maintain a stable pH level. This is because it can release oxygen molecules when the blood becomes too acidic, thereby reducing the acidity and helping to restore the pH balance.



Reasoning for the Role of Oxyhaemoglobin


Oxyhaemoglobin is a molecule found in red blood cells that is formed when oxygen binds to the haemoglobin protein. This molecule plays a critical role in the transport of oxygen from the lungs to the tissues of the body. However, it also has the ability to influence the pH of the blood and act as a buffer.

When the blood becomes too acidic, it can have harmful effects on the body's cells and tissues. Oxyhaemoglobin can help to counteract this acidosis by releasing oxygen molecules to the tissues. This process is known as the Bohr effect, and it helps to restore the pH balance of the blood.

On the other hand, when the blood becomes too alkaline, oxyhaemoglobin can bind to hydrogen ions, which helps to reduce the alkalinity of the blood and restore the pH balance. This ability to act as a buffer is critical for maintaining a stable pH level in the blood, which is necessary for the proper functioning of the body's cells and tissues.

In conclusion, oxyhaemoglobin is considered neutral but can act as a buffer in the blood to help maintain a stable pH level. Its ability to release oxygen molecules and bind to hydrogen ions allows it to counteract acidosis and alkalosis, respectively, and restore the pH balance of the blood.
