This science fair project was performed to attempt the purification of soybean peroxidase
Difficulty: High school
This science fair project was conducted to compare the effectiveness of different forms of enzymes in removing grease from a grease trap. Tests were done using liquid, powder and solid enzymes to breakdown fat, oil and grease that were collected from a grease trap.
Difficulty: Middle school
This experiment was conducted to find out how different temperatures will affect the chemical reaction of the enzyme Catalase in hydrogen peroxide.
Difficulty: High school
This experiment was conducted to find out how different temperatures will affect the chemical reaction between the enzyme peroxidase and hydrogen peroxide.
Difficulty: High school
This science fair project was done to find out the effect of using tea leaves as fertilizer for enhancing plant growth. Testing was done using the rose plant planted in soil mixed with tea leaves.
Difficulty: Middle school
Students quantitatively assay the activity of the enzyme peroxidase extracted from a turnip or other vegetable. They form hypotheses regarding how the rate of an enzyme-catalyzed reaction is affected by concentration of the enzyme, the pH of the reaction, temperature, inhibitors, and conduct experiments to test their hypotheses. Collected data are compiled in tables and graphs for use in a lab rep

In this investigation, amylase is the enzyme, and starch is the substrate, i.e. the substance it acts upon. In fact this work should add to your knowledge about the process of digestion which occurs in your body. This practical work is designed to give you some experience about: i) how enzymes work, using amylase as an example ii) what a "control" experiment tells you iii) how to carr

The purpose of this experiment was to determine the rate of dissolution for several dairy digestive supplements, lactase pills. I became interested in this idea because I am lactose intolerant and I wanted to buy the fastest acting pill. The information gained from this experiment would help consumers know which brand of lactase pills will dissolve fastest so they can make the best purchasin

Enzymes are very large and complex organic molecules that are synthesized by the cell to perform very specific functions. These biological catalysts are important because they speed up the rate of the reaction they catalyze that would otherwise be too slow to support life. Catalase is an enzyme present in the cells of plants, animals and aerobic (oxygen requiring) bacteria. It promotes the convers

Several other factors besides enzyme concentration can affect the rate and efficiency of enzymatic reactions, including pH, temperature, and the presence or absence of the cofactors or enzymatic inhibitors we discussed in class. In this lab, we will investigate how these factors affect enzymatic reactions by observing the effect of the two enzymes (catechol oxidase and amylase) on their respective
