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.) WebAt those times, myoglobin releases oxygen to sustain aerobic metabolism in the muscle.
