Molecular model transfer function

Today I got around to trying out a simplified molecular version of the gate model that will replace my hyperbolic function.



The kinetics are all arbitrary for the model, but the shape of the transfer function looks even better than the made-up model from before. There's an almost perfectly linear section in the middle -- it looks more made-up than my made-up model! This is assuming that all three reactions have the same strength. Next, I need reasonable terms for the three reaction rates.
