Asymptotics and numerical analysis for enzymatic auxiliary reactions
In this paper we study the mathematical model of auxiliary (or coupled) reactions, a mechanism
which describes several chemical reactions. In order to apply singular perturbation techniques, we determine
an appropriate perturbation parameter ǫ (which is related to the kinetic constants and initial conditions of the
model), the inner and outer solutions and the matched expansions of the solutions, up to the first order in ǫ, in
the total quasi-steady-state approximation (tQSSA) framework. The contribution of these expansions can be
