Test students' ability to analyze initial-rate versus substrate-concentration data collected with and without inhibitors to identify inhibition type (competitive, noncompetitive, uncompetitive, or mixed) and to calculate kinetic parameters (Km, Vmax, and Ki). Require use of Lineweaver–Burk or Eadie–Hofstee plots and/or nonlinear regression, presentation of calculation steps, interpretation of diagnostic plot features, and brief justification of conclusions.
