Hemoglobin synthesis takes place in all except _.
Correct answer: B. Erythrocyte
- A. Reticulocytes
- B. Erythrocyte
- C. Basiophilic erythroblasts
- D. None of these
Explanation
Option A: Reticulocytes are immature red blood cells that still contain remnants of ribosomes and RNA. They are produced in the bone marrow and go through a process of maturation before becoming fully functional erythrocytes. During their maturation, reticulocytes synthesize hemoglobin, the protein responsible for carrying oxygen in the blood.Option B: Erythrocytes, also known as red blood cells, are the mature form of red blood cells. They have a distinct biconcave shape and lack a nucleus and most organelles. Mature erythrocytes are specialized for oxygen transport and do not have the ability to synthesize new proteins, including hemoglobin. Their primary function is to circulate in the bloodstream and transport oxygen from the lungs to the body tissues.Option C: Basophilic erythroblasts are nucleated precursor cells of red blood cells found in the bone marrow. They undergo a series of maturation steps to develop into reticulocytes, which eventually become mature erythrocytes. During their maturation, basophilic erythroblasts actively synthesize hemoglobin to support the oxygen-carrying capacity of the developing red blood cells

About Human Heart
The human heart is a four chambered muscular pump that maintains double circulation through the pulmonary and systemic circuits. Questions cover atria, ventricles, valves, major blood vessels, the cardiac cycle, pressure changes, the conduction system and ECG, while distinguishing arteries and veins from the chambers that receive or eject blood.
