Question

What is hemozoin?
A. Undigested part of blood in trophozoite of Plasmodium
B. Blood pigments of anopheles
C. Decomposed blood in merozoites
D. Granules in the blood of infected person

Answer 1

Hint: Blood-feeding parasites produce hemozoin or hemozoin as a byproduct of their digestion. It is frequently generated as a result of blood digestion. Parasites emit significant amounts of free-heme after digesting haemoglobin, and free-heme is harmful to cells. As a result, the parasites transform free-heme into hemozoin, an insoluble, crystalline form.
Due to the importance of hemozoin for parasite life, current and upcoming antibiotics prevent the synthesis of hemozoin, killing parasites.

Complete answer:
Option A: Haemozoin is an undigested and discarded remains of malarial parasites' consumption of blood, particularly the trophozoite stage of Plasmodium.
So, option A is correct.
Option B: Hemozoin is an undigested and discarded byproduct of the ingestion of blood by malarial parasites, particularly the trophozoite stage of Plasmodium.
So, option B is incorrect.
Option C: Blood-feeding parasites produce hemozoin or hemozoin as a byproduct of their digestion.
So, option C is not correct.
Option D: Hemozoin is a waste product created by certain blood-feeding parasites, such as malaria parasites, during the digestion of blood.
So, option D is not correct.

So, the correct answer is “Option A”.

Note:
For the past \[120\] million years, Plasmodium has evolved in lockstep with vertebrate evolution. As a result, the Plasmodium has evolved through new hosts, followed by adaptation to those hosts, demonstrating the major rationale for the Plasmodium's evolution. P. gaboni, P. falciparum, P. ovale, and P. reichenowi are among the Plasmodium species that have been isolated from chimps. Gorillas are separated from the other species. P. mexicanum and P. floridense are Plasmodium parasites found in reptiles, whereas P. relictum and P. juxtanucleare are Plasmodium parasites found in birds.
