GATE Chemical Reaction Engineering: Enzyme kinetics: Michaelis-Menten and Monod models – Previous Year Questions

3 GATE previous year questions on Enzyme kinetics: Michaelis-Menten and Monod models (Chemical Reaction Engineering, Chemical Engineering) with answers and explanations, from every paper.

  1. GATE 2022 CH Q27 (1 mark, Multiple choice) – In an enzymatic reaction, an inhibitor (I) competes with the substrate (S) to bind with the enzyme (E), thereby reducing the rate of product (P)…
  2. GATE 2024 CH Q62 (2 marks, Numerical answer) – A chemostat with cell recycle is shown in the figure. The feed flow rate and culture volume are F = 75 L h-1 and V = 200 L, respectively. The glucose…
  3. GATE 2025 CH Q31 (1 mark, Multiple select) – Consider an enzymatic reaction that follows Michaelis-Menten kinetics. Let K M, S, and V max denote the Michaelis constant, substrate concentration,…
