Do not discuss why something occurred, just state what occurred. Principles of enzyme catalysis using catalase. The experiment activities below explore how enzymes react under different experimental conditions such as temperature, pH, and time. Each enzyme has an active site, which is where the reaction takes place (Figure 1). Some vegetarian students may wish to opt out of handling liver samples, and this should be respected.
Catalase Enzyme Lab Answer Key Concept Map
The enzyme catalase, found in potato juice, was used for the catalyst along with a substrate known as hydrogen peroxide (H2O2). However, a catalyst does not take part in the reaction itself—so how does this work? It is use of the scientific method that differentiates science from other fields of study that attempt to improve our understanding of the world. Exploring Enzymes | STEM Activity. As pH comes closer to a neutral pH the enzyme is at its greatest effectiveness. Students will use liver, manganese, and potato as catalysts.
Catalase Enzyme Lab Answer Key Page 2
Collect the paper discs out of your hole puncher (or hit up the copy center at your school). The second tube's temperature setting was at room temperature until a temperature of 21°C was reached. When Catalase, and Hydrogen Peroxide are reacting you can tell because many bubbles are produced fast. Recent flashcard sets. Once one of both compounds is depleted, the product formation stops.
