Title: The Effect of Temperature on Enzyme Activity Abstract:
The purpose of this experiment was to determine how temperature affects the activity of the enzyme amylase. Three different temperatures were tested: 10°C, 25°C, and 45°C. The results showed that the rate of reaction increased as the temperature increased up to 45°C. However, at temperatures above 45°C, the rate of reaction began to decrease due to denaturation of the enzyme. The optimal temperature for amylase activity was found to be 45°C. These findings have important implications for the use of enzymes in industrial processes. Introduction:
Enzymes are biological catalysts that speed up chemical reactions without being consumed in the process. They are essential for life and are used in a wide range of industrial processes. Enzyme activity is affected by a number of factors, including temperature, pH, and substrate concentration. Temperature is one of the most important factors affecting enzyme activity. Enzymes have an optimal temperature at which they work most efficiently. At temperatures above or below this

optimal temperature, the rate of reaction decreases. At very high temperatures, enzymes can become denatured and lose their ability to function. Materials and Methods:
The experiment was performed using a solution of amylase enzyme and starch. Three test tubes were prepared, each containing 5 mL of the enzyme solution and 1 mL of starch solution. The test tubes were then heated to three different temperatures: 10°C, 25°C, and 45°C. The temperature was controlled using a water bath. A control test tube was also prepared, containing the same amount of enzyme and starch, but no temperature was applied. The reaction was allowed to proceed for 10 minutes, after which the test tubes were removed from the water bath and the absorbance of each solution was measured using a spectrophotometer. Results:
The results showed that the rate of reaction increased as the temperature increased up to 45°C. At 10°C, the rate of reaction was very slow, with an absorbance reading of 0.010. At 25°C, the rate of reaction was faster, with an absorbance reading of 0.035. At 45°C, the rate of reaction was the fastest, with an absorbance reading of 0.080. However, at temperatures
