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: -Each hemoglobin molecule can carry four molecules of oxygen, one in each polypeptide.
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: -Hemoglobin (Hb), which is contained in red blood cells, serves as the oxygen carrier in the blood. Each heme group contains an iron atom, and this is responsible for the binding of oxygen. The mammalian hemoglobin molecule can bind (carry) up to four oxygen molecules.
