Mature mammalian red blood corpuscles lack a nucleus and cell organelles. Losing the mitochondria specifically gives the RBC which advantage?
AIt can divide more rapidly than other cells
BIt can produce antibodies against infection
CIt can deliver all its oxygen to the tissues
DIt can engulf and digest invading bacteria
Answer & Solution
Correct answer: C. It can deliver all its oxygen to the tissues
1. Mature mammalian RBCs lose the nucleus and all cell organelles.
2. The question asks for the gain from losing mitochondria specifically.
3. Mitochondria normally burn oxygen during cellular respiration.
4. Option A (faster division) is wrong because losing the nucleus actually removes the ability to divide.
5. Option B (antibodies) is a lymphocyte function, not an RBC one, so it is a trap.
6. Option D (engulfing bacteria) is a phagocyte (monocyte) role, not an RBC one.
7. Without mitochondria the RBC consumes none of the oxygen it carries.
8. So all the oxygen is delivered to the tissues, option C.
