The interaction between a specific microorganism and a common household chemical results in a readily observable reaction. This occurs because the microorganism contains an enzyme that accelerates the decomposition of the chemical compound. A notable example involves single-celled fungi and hydrogen peroxide; the fungi possesses an enzyme which drastically increases the rate at which hydrogen peroxide breaks down into water and oxygen.
This process is biologically significant due to the cellular need to manage reactive oxygen species. Hydrogen peroxide, while having applications in disinfection, is inherently toxic to cells. The enzymatic breakdown mitigates this toxicity. Furthermore, the reaction serves as a simple and effective demonstration of enzyme catalysis, a fundamental principle in biochemistry, making it useful in educational contexts and scientific experimentation. Early investigations into enzymatic activity utilized similar reactions to understand the nature and speed of biological catalysts.
