The Michaelis-Menten enzyme reaction scheme is described, and the
pseudo-steady state approximation which enables it to be solved, are
described, from the point of view of singular perturbation
theory. Modifications in the presence of a further inhibiting
substrate are also analysed, and the exercises consider further
variants, both in terms of reactions and parameter limits.
This was the first chapter in the original lecture notes (which
comprised the forerunners of chapters 9 to 15), and is perhaps written
in a more elementary frame of mind than necessary; on the other hand,
a course which starts here would need that approach.
