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.

Students will change the temperature In this lab, you will study an enzyme that is found in the cells of many living tissues. The name of the enzyme is catalase; it speeds up a reaction which breaks down hydrogen peroxide, a toxic chemical, into 2 harmless substances--water and oxygen. Light can also break down H 2 O 2 which is why the chemical is sold in dark containers. Students who complete the Enzyme Investigation lab can further explore enzymes with this lab on how concentrations of the substrate (hydrogen peroxide) and the enzyme ( catalase) can affect the rate of reaction. In the first experiment, students simply made a judgement about the amount of bubbling to indicate reaction speed, though this is a The enzyme studied in this lab was catalase.

Students will perform an enzyme assay and determine the rate of the enzymatic reaction. This activity is an alternative to Investigation 13-Enzyme Activity in College Board's AP Biology Lab Manual. First part is calculating rate under certain conditions. Second part is manipulating one variable to see its effect on enzyme activity (rate of reaction). PASCO Oxygen gas sensors used for second part.

Important Consideration: This laboratory is structured for five different temperatures. This may be very impractical for many classrooms. If heat blocks or water

The enzyme studied in this investigation was acid phosphatase. This enzyme can be identified by its ‘Enzyme Commission Number’ (EC number) which is 3.1.3.2. Now I will briefly discuss the enzyme kinetic properties of acid phosphatase. The enzyme acid phosphatase catalyses the removal of phosphate group from organic molecules.

First part is calculating rate under certain conditions. Second part is manipulating one variable to see its effect on enzyme activity (rate of reaction).

Substrate concentration, temperature, and pH all affect the chemical reaction. In this lab, the enzyme catalase In this lab, enzyme kinetics are examined utilizing various experimental techniques, including measurements of absorbance and temperature, to determine the effects on reaction rate dependent on enzyme and substrate concentration, temperature, and substrate specificity, as well as calculate the concentration of enzymes and substrates, V o The purpose of this enzyme activity lab was to determine what impacts the rate of reaction for the reaction: 2H2O2 –> 2H2O + O2 (gas). In the experiment that my lab partners and I constructed, we decided to test if pH and temperature had an impact on the rate of the reaction.
