MICROANATOMY

Detailed explanation-1: -The hemoglobin molecule has four binding sites for oxygen molecules: the iron atoms in the four heme groups. Thus, each Hb tetramer can bind four oxygen molecules.

Detailed explanation-2: -Hemoglobin is a protein found in red blood cells. It contains iron, which allows it to transport oxygen. Each hemoglobin molecule can bind up to four oxygen molecules. This way, it can transport the oxygen from the lungs to the tissues that need it.

Detailed explanation-3: -View this answer. Hemoglobin that has oxygen attached is called c. oxyhemoglobin. Hemoglobin is responsible for carrying around 98.5% of the oxygen in the bloodstream.

Detailed explanation-4: -The mammalian hemoglobin molecule can bind (carry) up to four oxygen molecules.

Detailed explanation-5: -Hemoglobin contains iron, which allows it to pick up oxygen from the air we breathe and deliver it everywhere in the body. You can think of hemoglobin as the iron ("heme"), oxygen transport protein, ("globin") found in red blood cells. It’s the hemoglobin that gives red blood cells their color, too.
