Question 2

Mature mammalian erythrocytes (red blood cells) lose their nucleus, ribosomes, and mitochondria during their development in the bone marrow.

Which statement about respiration in mature erythrocytes is correct?

They undergo aerobic respiration because they are constantly exposed to high concentrations of oxygen in the blood.

They do not carry out any metabolic respiration because they lack a nucleus to regulate metabolic pathways.

They generate energy by aerobic respiration using oxygen released from haemoglobin.

They respire anaerobically via glycolysis because they lack mitochondria.
