Question

definition of hemoglobin...​

Answer 1

• Hemoglobin, sometimes written hemoglobin, is an iron-containing protein found in the blood of many animals, particularly in vertebrates' red blood cells (erythrocytes), which carries oxygen to the tissues.
• With oxygen, hemoglobin creates a reversible, unstable connection.
• It's termed oxyhemoglobin when it's oxygenated and is brilliant red; it's purplish blue when it's deoxygenated.
• Red blood cell-forming cells in the bone marrow create hemoglobin. Hemoglobin is broken down as red blood cells die.
• iron is salvaged, transported to the bone marrow by proteins called transferrins, and used in the production of new red blood cells.
• the rest of the hemoglobin becomes bilirubin, a chemical excreted in the bile and responsible for the yellow-brown colour of the feces.
