What is haemozoin and what is its effect ?

Explanation

**Step-by-Step Solution:**

1. **Definition of Hemozoin**: Hemozoin is a toxic pigment that is produced as a byproduct when red blood cells (RBCs) are ruptured. This rupture occurs during the life cycle of the malaria-causing protozoan, Plasmodium.

2. **Connection to Malaria**: Malaria is a disease caused by the protozoan Plasmodium, which has several species that can infect humans. The disease is characterized by the multiplication of the Plasmodium parasite in the liver and subsequent invasion of red blood cells.

3. **Mechanism of Action**: When the Plasmodium parasite invades and multiplies within red blood cells, it eventually causes the cells to rupture. This rupture releases hemoglobin and other cellular components, including hemoglobin breakdown products, one of which is hemozoin.
