The hypothesis that increasing temperature would enhance catalase enzyme activity until denaturation occurs was strongly supported by the experimental data. The results demonstrated optimal enzyme activity at 37°C with oxygen production of 15ml, representing a 650% increase from the 5°C baseline of 2ml. This finding aligns with the principle that higher temperatures increase molecular kinetic energy and enzyme-substrate collision frequency. The dramatic decrease in activity at 60°C (8ml) and near-complete loss at 80°C (1ml) confirms enzyme denaturation at elevated temperatures, where protein tertiary structure is disrupted. The unexpectedly low activity at 20°C may have resulted from insufficient reaction time or temperature equilibration. Potential error sources including temperature fluctuations and timing variations likely contributed to data variability. More precise temperature control and standardized measurement intervals would improve accuracy in future trials. These findings have significant biological relevance, explaining why human body temperature (37°C) optimizes enzymatic function, and why fever can be dangerous. The results also demonstrate industrial applications for enzyme-based processes requiring temperature optimization. Future investigations could explore pH effects on catalase activity, test different substrate concentrations, or examine other enzymes' temperature responses to broaden understanding of enzyme kinetics and environmental factors affecting biological catalysis.
