Carbonic anhydrase is a zinc-containing enzyme present in RBCs. This enzyme, catalyzes the reversible reaction of carbon dioxide with water to form carbonic acid.

Carbonic Anhydrase in Leucocytes:
Leucocytes, also known as white blood cells, are a crucial part of the immune system and play a significant role in fighting off infections and diseases. Carbonic anhydrase is an enzyme that catalyzes the reversible hydration of carbon dioxide, which is essential for various physiological processes in the body.

Function of Carbonic Anhydrase:
Carbonic anhydrase is responsible for maintaining the acid-base balance in the body by catalyzing the conversion of carbon dioxide and water into carbonic acid, which then dissociates into bicarbonate ions and protons. This process is essential for regulating pH levels in tissues and organs.

Presence in Leucocytes:
Studies have shown that carbonic anhydrase is present in leucocytes, specifically in the cytoplasm of these white blood cells. The enzyme plays a crucial role in various functions of leucocytes, including cell adhesion, migration, and phagocytosis. Carbonic anhydrase helps leucocytes to maintain their pH balance, which is essential for their proper functioning in the immune response.

Conclusion:
In conclusion, carbonic anhydrase occurs in leucocytes, specifically in the cytoplasm of white blood cells. The enzyme plays a vital role in maintaining the pH balance of leucocytes and is essential for their proper functioning in the immune system.
