Which of the following explains the binding of inorganic component in structure found in erythrocytes?

Correct answer: C. O2 with Fe of haem

  • A. CO with organic portion of haem
  • B. CO2 with NH2 group of haemoglobin
  • C. O2 with Fe of haem
  • D. H+ with COOH group of haemoglobin

Explanation

•The binding of the inorganic component in the structure found in erythrocytes (red blood cells) involves the binding of oxygen (O2) with the iron (Fe) component of the hemoglobin molecule. Hemoglobin is the protein present in red blood cells that is responsible for carrying oxygen from the lungs to the body's tissues. •When oxygen is inhaled, it diffuses into the blood in the lungs and binds to the iron atoms (Fe) present in the heme groups of hemoglobin. Each hemoglobin molecule can bind up to four oxygen molecules, forming a stable complex called oxyhemoglobin. This oxyhemoglobin complex is then transported by the bloodstream to deliver oxygen to various tissues and organs throughout the body.

About Circulation

The circulatory system covers the chambers, valves and conducting pathway of the human heart, along with the cardiac cycle and control of heartbeat. It compares arteries, veins and capillaries by structure and function, and explains how the lymphatic system returns tissue fluid, transports absorbed fats and supports immunity.
