WebThe O 2 pressure at which half of the molecules in a solution of myoglobin are bound to O 2 (P 1/2) is about 1 mm Hg (1.3 × 10 −3 atm). Figure 4.2.2: Oxygen Binding to Myoglobin and Hemoglobin. (a) The Fe 2+ ion in deoxymyoglobin is high spin, which makes it too large to fit into the “hole” in the center of the porphyrin. WebMar 15, 2024 · This model implies what is described as infinitely cooperative binding of oxygen. (Notice that the Hill equation becomes: Y = L/ [K D + L], when n =1 (as in the case with myoglobin, and in any equilibrium expression of the form M+L↔ML. Remember plots of ML vs L or Y vs L gives hyperbolas, with K D = L at Y = 0.5.) daddy coming home
