Adult human RBCs are enucleate. Which of the following statement(s) is/are most appropriate explanation for this feature?(a) They do not need to reproduce(b) They are somatic cells(c) They do not metabolize(d) All their internal space is available for oxygen transport
- AOnly (a)
- B(a), (c) and (d)
- C(b) and (c)
- DOnly (d)
Solution & Step-by-step Explanation
The primary function of RBCs is the transport of respiratory gases. The loss of the nucleus (and other organelles like mitochondria) during maturation provides more internal space to accommodate more Haemoglobin, thereby maximizing oxygen-carrying capacity.
