WebIn red blood cells, the oxygen-binding curve for hemoglobin displays an S shaped called a sigmoidal curve. A sigmoidal curve shows that oxygen binding is cooperative; that is, when one site binds oxygen, the probability that the remaining unoccupied sites that will bind to oxygen will increase.

Webyes. A stereotypic enzyme with M.M kinetics is hyperbolic. V increases with S, and levels off at V max. Some proteins like hemoglobin have sigmoidal (S shaped) curves. Hemoglobin has 4 O2 binding subunits. Binding the first oxygen, promotes binding a second, which promotes binding a third and so on..hence the S shaped curve. March test-taker flymo blower sparesWebThe binding of oxygen to hemoglobin can be plotted as a function of the partial pressure of oxygen in the blood (x-axis) versus the relative Hb-oxygen saturation (y-axis).
