摘要內容：
In living cells, biochemical reactions form intricate networks, such as metabolic pathways, that give rise to essential cellular functions. However, the complexity of these network structures, together with our limited knowledge of their detailed kinetics, makes it challenging to understand how these functions emerge from network dynamics.
In this presentation, we introduce a method that enables us to determine system responses based solely on network structure. Using this method, we show that the effects of parameter perturbations on the steady state are confined to subnetworks satisfying specific topological conditions. Furthermore, we show that these subnetworks govern the steady-state bifurcations of reaction systems, including which parameters control the onset of bifurcations and which chemical species exhibit bifurcating behavior. Our findings demonstrate that network topology can underlie biological robustness and plasticity, two fundamental characteristics of living systems.
