WebApr 13, 2024 · As hemoglobin is a tetrameric protein, each molecule has four binding sites for oxygen, and it is well-known that the binding of the first oxygen molecule enhances the binding of the remaining oxygens; this positive cooperativity results in a sigmoidal binding curve (i.e., narrow, switch-like responses) allowing for efficient oxygen shuttling. http://guweb2.gonzaga.edu/faculty/cronk/CHEM245pub/hemoglobin.html

WebCooperative binding occurs in a molecular binding system where two or more ligand molecules can bind to a receptor molecule. Binding can be considered "cooperative" if the actual binding of the first molecule of the ligand to the receptor changes the binding affinity of the second ligand molecule.

WebJan 17, 2024 · The binding affinity of hemoglobin for oxygen is cooperative. It is increased by the oxygen saturation of the molecule. Binding of an initial oxygen molecule influences the shape of the other binding sites. This makes binding more favorable for additional oxygen molecules. blyth planningWebJun 16, 2009 · The famous team of Jacques Monod, Jeffries Wyman and Jean-Pierre Changeux proposed a different model for oxygen binding by hemoglobin.
