Description

Write a lab report that includes the following:

1. Title page in APA Format: descriptive title, your name, course name, semester

2. Introduction: general background information about enzymes and specific information about your chosen enzyme (CATALASE), the question(s) that you are asking and a clear hypothesis for your experiment.

3. Design an experiment. Provide a detailed description of the materials and methods used to conduct the experiment. Identify control and experimental samples, as well as independent and dependent variables. Also include the methods used for data collection and analysis.

4. Conduct the experiment and record your results. Take picture of results. What did you observe? Present your data in table and/or graph format. Remember to label everything and include the unit of measure with all numbers.

5. Use your knowledge of enzymes and pH to interpret and discuss your results. It may be necessary for you to refer to the additional information resources. What effect does the acidic treatment have on enzyme activity? Did you get the expected results? Explain.

6. State a specific and accurate conclusion. Is your hypothesis supported by the results? Looking back, how could you have improved your experiment?

7. Include a list of references to all information sources used in APA format.


I KNOW THAT QUESTIONS 4 THROUGH 6 MIGHT BE IMPOSSIBLE WITHOUT THE MATERIALS BUT PLEASE LET ME KNOW IF YOU CANNOT COMPLETE THE FULL REPORT BEFORE PROCEEDING FORWARD WITH ACCEPTING THIS ASSIGNMENT.

Testing Catalase Activity Rate
Introduction
Most organisms are able of enzymatically decomposing hydrogen peroxide. The enzymes
(globular proteins) used in the decomposition process are responsible for many chemical
activities these living organisms but are not altered or destroyed (Matthews, 2017). Due to their
efficiency, enzymes can be used repeatedly in many reactions. The enzymatically enhanced
processes are controlled both pH and temperature. Many organisms have their temperate range
within which they survive and so to their enzymes. So, a too basic or acidic conditions makes the
enzymes irreversibly denatured.
Hydrogen peroxide is one of the most toxic chemicals in various living organisms. So,
these organisms destroy hydrogen peroxide with the help of enzymes before causing any harm to
the body of the organisms as shown by the chemical equation below (In Tunon & In Moliner,
2017).

Catalase is one in several examples of enzymes that are responsible for the chemical reaction
taking place in bodies of many organisms. It is found in animals. This experiment aimed to test
the activity rate of Catalase enzyme under different pH values, temperatures, and enzyme
concentration. The null hypothesis of the experiment was that there is no effect of temperature,
pH, and enzyme concentration on the activity rate of Catalase enzyme.

Testing Catalase Activity Rate
Abstract
Enzymes work under controlled conditions of temperature, pH, and concentration of
substrate, among other influential factors. Beyond the extremes of these conditions, enzymes are
denatured. In an experiment to test the influence of hydrogen concentration on the catalase’s
activity rate using yeast-sodium alginate (yeast spheres), graduated cylinder method was used.
The methodology involved preparing yeast spheres that had enzyme concentration before the
actual experiment was carried out. The rate of catalase activity was found by recording distance
and time traveled by the yeast spheres to reach the top surfaces of the solution at different...
