Webhemoglobin, also spelled haemoglobin, iron-containing protein in the blood of many animals—in the red blood cells (erythrocytes) of vertebrates—that transports oxygen to the tissues. Hemoglobin forms an unstable reversible bond with oxygen. In the oxygenated state, it is called oxyhemoglobin and is bright red; in the reduced state, it is purplish blue. … WebEach hemoglobin molecule can bind up to four oxygen molecules. Hemoglobin exhibits what we call cooperative binding, as oxygen binding increases the affinity of hemoglobin for more oxygen. …. Cooperative binding ensures adequate oxygen transport and delivery to our metabolizing tissues.
