Test graduate students' understanding of how thermodynamic driving forces (ΔG°', ΔG, reaction quotients) and enzyme kinetics (Michaelis–Menten parameters, allosteric regulation, Vmax/Km) jointly determine steady‑state metabolic pathway fluxes. Scope includes distinguishing near‑equilibrium versus far‑from‑equilibrium reactions, identifying thermodynamic bottlenecks and kinetically rate‑limiting steps, predicting flux responses to changes in metabolite concentrations, enzyme activities, and cofactor ratios, and applying qualitative concepts from metabolic control/flux control analysis to explain control distribution and implications for pathway engineering.
