An ODE-based model of a simple catalytic reaction network is discussed, with particular attention to the influence of the kinetic rates of the various reactions on the overall dynamical behavior. Several distinct scenarios are described and analyzed, highlighting the importance of the fine tuning of the kinetic parameters in regard to the competition for survival of different dynamical structures, i.e. autocatalytic cycles, on the one hand, and linear reaction chains, on the other, which access the same limited resources. Finally, the importance of a possible compartmentalization of this dynamical system within protocell-like structures is discussed, with explicit regard to the competitive advantage that is supposed to characterize the dynamics of autocatalyitic cycles.
