Substrate = H 2O 2 … Timing and Length of Lab This investigation requires approximately three to four lab periods of about 45 minutes each, depending on student interest and how far students want to take their investigation. The skills set requires approximately 40 minutes for students to work through it. Gautsch1 Lab 6: Enzymes John Gautsch September 24, 2014 Abstract Lab six requires students to observe the effects of pH and enzyme concentration on catecholase activity. Enzymes are organic catalysts that can affect the rate of a chemical reaction depending on the pH level and the concentration of the enzyme. The four factors that can be explored in this lab are: pH, temperature, enzyme and substrate concentration, and competitive inhibition. This lab provides enough reagents for eight lab groups to each pursue at least two of these investigations. Each lab group will start by creating a dilution series of fluorescein to use as a visual standard scale.

There was also a neutral buffer in each of the chemical mixtures. The neutral buffer regulated the pH to around 7. We got a color palette and once we mixed each together, we observed and saw a change in the color of the substance. Enzyme + Substrate --> Enzyme-Substrate Complex --> Enzyme + Product(s) + ΔG For this investigation the specific reaction is as follows: Catalase + Hydrogen Peroxide --> Complex --> Catalase + Water + Oxygen 2H 2 O 2 → 2H 2 O + O 2 (gas) Notice that the catalase is present at the start and end of the reaction. Like all catalysts, enzymes are Se hela listan på This lab fits in Chapter 2 (Chemistry of Life) of Freshman Biology with enzyme activity.
