Catalase and Hydrogen Peroxide

Catalase speeds decomposition of hydrogen peroxide into water and oxygen.

PRACTICAL WORKBENCH · EXPERIMENT 15

🧪 Enzyme assay bench: Measure catalase activity

Catalase decomposes hydrogen peroxide into water and oxygen; foam is a rough indicator, not a precise rate measurement.
