I. Abstract

This study investigates the impact of temperature on the activity of the enzyme catalase. Catalase plays a critical role in breaking down hydrogen peroxide into water and oxygen.

The experiment was conducted by measuring the rate of oxygen production from the decomposition of hydrogen peroxide at various temperatures.

The results indicate an optimal temperature for catalase activity and provide insights into the enzyme's temperature sensitivity.

II. Introduction

Enzymes are biological catalysts that accelerate chemical reactions in living organisms. One crucial factor that influences enzyme activity is temperature. Understanding the temperature dependence of enzyme activity is essential for elucidating enzyme function in physiological and environmental contexts.

Catalase, an enzyme found in cells, catalyzes the decomposition of hydrogen peroxide into water and oxygen. This study aims to investigate how temperature affects catalase activity, with a focus on identifying the optimal temperature for enzyme function.

III. Materials and Methods

• Catalase enzyme solution

• Hydrogen peroxide (H2O2)

• Water baths set at temperatures of 10°C, 25°C, 37°C, 50°C, and 70°C.

• Spectrophotometer

• Test tubes

• Stopwatch

The experiment was conducted by preparing a series of catalase enzyme solutions and incubating them at different temperatures.

The rate of enzyme activity was measured by monitoring the production of oxygen gas from the decomposition of hydrogen peroxide using a spectrophotometer. The experiment was repeated multiple times to ensure reproducibility.

IV. Results

The results show that catalase activity increases with temperature, reaching a peak at around 37°C. At temperatures above 37°C, the enzyme activity decreases, indicating denaturation of the enzyme.

These findings suggest that catalase has an optimal temperature for activity and is sensitive to higher temperatures.

V. Discussion

The results of this study support the hypothesis that temperature affects enzyme activity. The observed decrease in catalase activity at high temperatures is consistent with the denaturation of the enzyme.

These findings have implications for understanding enzyme function in biological systems and highlight the importance of temperature regulation in maintaining enzyme activity.

VI. Conclusion

In conclusion, this study demonstrates that temperature significantly influences the activity of the enzyme catalase. The optimal temperature for catalase activity was found to be around 37°C, with a decrease in activity at higher temperatures.

These findings contribute to our understanding of enzyme function and have potential applications in various fields, including biotechnology and medicine.
