Scientific Methodology & Enzyme Activity

Laboratory 2: Scientific Methodology & Enzyme Activity Objective: The purpose of this experiment was to simply measure oxygen production rates released from decomposed hydrogen peroxide under different conditions (concentration of enzymes, temperature, and PH level). Hypothesis: Part a: If different amounts of enzyme solution are added to the hydrogen peroxide, then the highest amount of enzymes will have the greatest reaction rate because enzymes catalyze reactions, meaning more oxygen will be produced quicker. Part b: If different temperatures are used to catalyze enzyme activity, then the lowest temperature would produce the quickest reaction rate because enzymes can become denaturized at higher temperatures Part c: If different amounts of pH are used to catalyze the reaction, then the concentration with pH…
