Bring complex enzyme kinetics concepts to life with this comprehensive and interactive online catalase simulation! Accessible anywhere with an internet connection via a simple link provided in the downloadable PDF, this virtual lab provides a robust platform for students to investigate enzyme function without the need for complex wet lab setups or hazardous materials.

Explore Key Concepts Interactively:

Basic Kinetics: Students manipulate temperature, pH, enzyme concentration [E], and substrate concentration [S] (Hâ‚‚Oâ‚‚) to observe their impact on the initial reaction rate (measured via Oâ‚‚ production).

Inhibitor Effects: Investigate the distinct mechanisms of:
Competitive Inhibition: Using Hydroxylamine Sulfate.
Non-Competitive Inhibition: Using Sodium Azide.
Michaelis-Menten Kinetics (Vmax Mode): A dedicated mode allows students to generate Rate vs. [S] data, visualise Michaelis-Menten plots, and explore the effects of competitive and non-competitive inhibitors on Vmax.

Molecular Visualisation: A dynamic animation window shows catalase enzymes, substrates, inhibitors, and products interacting in real-time, including visual cues for denaturation and inhibition.

Data Generation & Analysis: The simulation generates realistic data (Oâ‚‚ ppm vs. time), calculates initial rates from the graph tangent, and presents results in tables. Data can be exported to CSV for further analysis in spreadsheet software.

Why Choose This Simulation?

Engaging & Visual: Captures student interest more effectively than static resources.
Safe & Cost-Effective: Eliminates safety concerns (Hâ‚‚Oâ‚‚, azide) and equipment costs.
Curriculum-Aligned: Covers essential topics in enzyme structure, function, and kinetics for standard and advanced biology courses.
Easy Access & Use: Runs online in any modern web browser (Chrome, Firefox, Edge, Safari). No installation needed! Students just click the link in the provided PDF.
Includes PDF Worksheet: Comes with a comprehensive student worksheet delivered as a PDF, containing the simulation link, background, step-by-step procedures for guided investigations (Temp, pH, [S], Inhibitors in Vmax mode), data tables, and analysis prompts.
