Question

Oxygen and hemoglobin bind in a reversible manner to form? a) Carboxyhemoglobin b) Oxyhemoglobin c) Methoglobin d) BPG

Answer 1

Oxygen and hemoglobin bind in a reversible manner to form  b) Oxyhemoglobin

• Hemoglobin is present in red blood cells which is responsible for travelling of oxygen through the blood.
• In the blood, hemoglobin reacts with oxygen to form oxyhemoglobin.
• Upon reaching different organs, oxygen detaches itself and  is released to different organs from the hemoglobin.
• Hence, the bonding of oxygen and hemoglobin is reversible for making the travel of oxygen possible through blood.

Answer 2

(b) is the correct option

Oxygen and hemoglobin bind in a reversible manner to form oxyhemoglobin:

• Hemoglobin is the pigment in the red blood cells (RBCs) that is responsible for the transportation of oxygen to various body parts. It is also the pigment that gives blood its red color.
• Hemoglobin binds with four molecules of oxygen and forms oxyhemoglobin. The binding happens in the lungs which has favorable conditions for the formation of oxyhemoglobin.
• The hemoglobin lets go of the bound oxygen when it reaches the required body parts.
