Web22 jul. 2024 · the lungs In the lungs hemoglobin becomes nearly saturated with oxygen such that 98% of the oxygen-binding sites are occupied. When hemoglobin moves to the tissues the saturation level drops to 32%. Thus a total of 98 – 32 = 66% of the potential oxygen-binding sites contribute to oxygen transport. See also why is the northern … WebThis 100% would mean all of the heme groups on all of the hemoglobin molecules or proteins have bound to oxygen. Zero means that none have. So when you have an environment with very little oxygen-- and this actually shows the cooperative binding-- so let's say we're just dealing with an environment with very little oxygen.
