Question

pls answer me its urjnt

Answer 1

Each subunit surrounds a central heme group that contains iron and binds one oxygen molecule, allowing each hemoglobin molecule to bind four oxygen molecules. ... Hemoglobin: The protein inside red blood cells (a) that carries oxygen to cells and carbon dioxide to the lungs is hemoglobin (b).

There are four hemes found in hemoglobin, one in each of the subunits. Therefore, myoglobin binds reversibly to only one oxygen molecule, while and hemoglobin binds four.

Answer 2

Hey friend here is your answer...........

Haemoglobin the essential component of red blood cells(erythrocytes) transports oxygen through the bloodstream from the lungs to all the tissues of the body. Haemoglobin also carries carbon dioxide back to the lungs to complete the process of respiration.


Myoglobin, an iron-containing protein in muscle, receives oxygen from the red blood cells and transports it to the mitochondria of muscle cells, where the Oxygen is used in cellular respiration to produce energy. Each myoglobin molecule has one heme prosthetic group located in the hydrophobic cleft in the protein.

Hope this helps you.
