WebJul 7, 2024 · Hemoglobin’s oxygen-binding curve forms in the shape of a sigmoidal curve. This is due to the cooperativity of the hemoglobin . As hemoglobin travels from the lungs to the tissues, the pH value of its surroundings decrease, and the amount of CO 2 that it reacts with increases. WebHemoglobin (Hb) is a complex protein molecule. It consists of four separate polypeptide chains called protein subunits. It is made up of two identical alpha-chains and two identical beta-chains. Each chain forms a 3-dimensional molecule with iron (Fe) intertwined in the center. Each Fe group is capable of combining loosely with one molecule of O 2.
