Haemozoin formed in malaria is produced by

Options

A. Globin part of haemoglobin
B. Haeme of haemoglobin
C. Cryptozoits
D. Dead leucocytes.

Answer

To answer the question "Haemozoin formed in malaria is produced by," we can break down the explanation into clear steps:

### Step-by-Step Solution:

1. **Understanding Haemozoin**:
- Haemozoin is a pigment that is produced as a byproduct during the digestion of hemoglobin by certain parasites.

2. **Identifying the Organism**:
- The primary organism responsible for malaria is the Plasmodium species, which is a blood-feeding parasite.

3. **Mechanism of Formation**:
- The Plasmodium parasite feeds on the host's red blood cells, where it digests hemoglobin, the protein responsible for transporting oxygen in the blood.

4. **Release of Heme**:
- During the digestion of hemoglobin, the Plasmodium releases a high quantity of free heme. Heme is a non-protein component of hemoglobin.

5. **Conversion to Haemozoin**:
- The excess free heme is toxic to the parasite, so it converts this heme into a polymerized form known as haemozoin, which is a waste product that is less harmful.

6. **Conclusion**:
- Therefore, haemozoin is produced by the Plasmodium species as a result of its digestion of hemoglobin from the host's red blood cells.

### Final Answer:
Haemozoin formed in malaria is produced by the Plasmodium species during the digestion of hemoglobin.
