Question

Trophoblasts of Plasmodium feed on.

• A. Haemoglobin molecules
• B. Cytoplasm of erythrocytes
• C. Globin part of haemoglobin
• D. Haematin part of haemoglobin

Answer 1

The correct option is C Globin part of haemoglobin

• The erythrocytic cycle of Plasmodium was first described by Camillo Golgi. Hence it is also called a Golgi cycle.
• This cycle is initiated either by the cryptozoites of the pre-erythrocytic cycle or the micro-metacryptozoies of the exo-erythrocytic cycle. In fresh RBC, these stages assume the spherical shape and transform into trophozoites or trophoblasts.
• These trophoblasts of Plasmodium digests the globin part of ingested hemoglobin and converts the soluble haem into insoluble crystalline hemozoin(malarial pigment).
• Hence Trophoblasts of Plasmodium feed on Globin part of hemoglobin.
• So, the correct answer is 'Globin part of hemoglobin'.
