metabolite changes in response to perturbation of one metabolite by 100%. (a) and (b) represent the changes in metabolites in case study 1 when X₂ is the perturbation target, derived using the reference and S-system model, respectively. (c) and (d) are the changes in case study 2 when X₁ is the perturbation target given by the reference and S-system model, respectively.
