This project investigates the impact of different catalysts on the rate of enzymatic reactions under various environmental conditions. The experiment will analyze how temperature, pH, and concentration influence the catalytic efficiency of enzymes.
If different catalysts are used in enzymatic reactions, then the reaction rate will vary depending on the catalyst type and environmental conditions.

Prepare control and experimental setups with test tubes.
Add equal amounts of hydrogen peroxide solution to each test tube.
Introduce yeast to the first set of test tubes as a catalyst.
Introduce potato extract to the second set of test tubes as a catalyst.
Vary the temperatures for each test tube and measure with a thermometer.
Adjust pH levels using a pH meter and solutions for each setup.
Start the reaction by adding catalysts to hydrogen peroxide.
Use a stopwatch to measure the time taken for oxygen bubbles to form.
Record the reaction time at different temperatures and pH levels.
Repeat steps for accuracy and calculate average reaction rates.
Analyze data to determine catalyst efficiency under varied conditions.
The expected results will show variation in reaction rates based on the type of catalyst used, with environmental conditions such as temperature and pH significantly influencing the outcomes.
