Question
Adult human RBCs are enucleated. Which of the following statement(s) is/ are the most appropriate explanation for this feature? (a) They do not need to reproduce (b) They are somatic cells (c) They do not metabolise (d) All their internal space is available for transport of oxygen
Only (a)
(a), (c) and (d)
(b) and (c)
Only (d)
According to the text, RBCs in most mammals are devoid of a nucleus and contain haemoglobin, which plays a significant role in the transport of respiratory gases. The biological reason for enucleation is to maximize the internal space available for haemoglobin, thereby increasing the oxygen-carrying capacity of the cell .
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Body Fluids and Circulation.
