Oxygen saturation curve of myoglobin
WebThe oxygen dissociation curve for hemoglobin has a sigmoid shape because of the co-operative binding of oxygen to the 4 polypeptide chains. On the other hand, Myoglobin is made up of a single polypeptide with only one … WebApr 12, 2024 · The amount of oxygen bound to the Mb protein (% saturation) is measured as a function of the percentage of oxygen (p O 2) in the blood. This yields a hyperbolic binding curve. In contrast, each hemoglobin (H b) can reversibly bind four O 2 (1 per subunit). When graphed, the H b binding curve is a sigmoidal curve which indicates subunit ...
