Hemozoin is

Options

A. a precursor of haemoglobin
B. a toxin from Streptococcus
C. a toxin from Plasmodium species
D. a toxin from haemophilus species

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Hemozoin":**
- Hemozoin is a compound that is produced by certain parasites, particularly the Plasmodium species, which are responsible for malaria.

2. **Chemical Nature of Hemozoin:**
- Hemozoin is described as an insoluble crystal. This means that it does not dissolve in water and has a solid crystalline structure.

3. **Toxicity of Hemozoin:**
- Hemozoin is classified as a toxin. It has toxic properties that can affect the host organism, contributing to the symptoms of malaria.

4. **Production of Hemozoin:**
- The malarial parasites (Plasmodium) produce Hemozoin in their food vacuoles. This is a part of their metabolic process when they digest hemoglobin from the host's red blood cells.

5. **Iron Content:**
- Hemozoin contains iron, which is a byproduct of the digestion of hemoglobin. This iron content is significant in the context of malaria pathology.

6. **Identifying the Correct Option:**
- Given the options:
- A precursor of hemoglobin (incorrect)
- A toxin from streptococcus (incorrect)
- A toxin from the plasmodium species (correct)
- A toxin from the hemophilius species (incorrect)
- The correct answer is that Hemozoin is a toxin from the plasmodium species.

**Final Answer:**
Hemozoin is a toxin produced by the Plasmodium species, which is responsible for malaria.
