Question

Mature RBCs lack

• A. Aerobic respiration
• B. Transcription
• C. DNA replication
• D. All of the above

Answer 1

The correct option is A Aerobic respiration

Erythropoiesis is the production of RBC. It takes place in the following steps.

1.) Multipotent stem cell differentiates into proerythroblast.

2) Proerythroblast begins producing hemoglobin, becoming erythroblast.

3) Erythroblast ejects nucleus, becoming a reticulocyte.

4) Reticulocyte escapes from bone marrow into the blood.

5) In 1-2 days, reticulocyte ejects remaining organelles, becoming erythrocyte.

As reticulocyte ejects remaining organelles including mitochondria. In mature RBCs, mitochondria are absent hence they lack aerobic respiration.

So, the correct answer is 'Aerobic respiration'.
