Assess students' ability to analyze metabolic flux distributions by processing 13C‑labeling datasets and applying stoichiometric models. Evaluate skills in selecting labeling strategies, constructing steady‑state stoichiometric or EMU models, estimating fluxes via MFA (and integrating FBA constraints where relevant), interpreting isotopomer patterns, testing parameter identifiability, and quantifying uncertainty and goodness‑of‑fit; include data preprocessing, constraint formulation, and biological interpretation of resulting flux maps.
