Oxygen saturation curve of myoglobin
WebMyoglobin saturation curve. The saturation of myoglobin is shown as a function of oxygen concentration. [Pg.174] For hemoglobin, n 2.8 ( sigmoidal saturation curve ), and for myoglobin, n = 1 ( hyperbolic saturation curve ). The efficiency of O2 transfer from hemoglobin to myoglobin is further enhanced by a decrease in pH since oxygen binding ...

WebMar 15, 2024 · Plots of Y (fractional saturation) vs L (pO 2) are hyperbolic for Mb, but sigmoidal for Hb, suggesting cooperative binding of oxygen to Hb (binding of the first oxygen facilitates binding of second, etc). Figure \(\PageIndex{11}\) shows fractional saturation (Y) binding curves vs dioxygen concentration (P O2) for both myoglobin and … WebMar 5, 2024 · The curve of oxygen binding to hemoglobin is sigmoidal typical of allosteric proteins in which the substrate, in this case oxygen, is a positive homotropic effector. …
WebNov 25, 2024 · An oxygen-binding curve is a plot that shows fractional saturation versus the concentration of oxygen. By definition, fractional saturation indicates the presence of … WebThe myoglobin oxygen binding curve has a p 50 of 2.8 torr. Mb therefore gives up little of its bound oxygen over the normal range of pO 2 levels in the blood. In sharp contrast to the myoglobin oxygen binding curve, the binding curve for hemoglobin is sigmoidal shaped.
WebThe relationship between the partial pressure of O 2 (P O 2 ) and percentage saturation of the Hb with O 2 is graphically illustrated by a curve called oxygen dissociation curve. The haemoglobin is most saturated with oxygen in the pulmonary vein, as this vein is carrying oxygenated blood from the Iungs towards the left auricle of the heart.
