from the experiment demonstrates that the catalase enzyme breaks down the hydrogen peroxide due to its harmful toxicity to the liver. In section A‚ the effect surface area has on the enzyme was tested. The results have proven that as the surface area increases‚ the reaction rate of the enzyme also increases. To illustrate‚ when the liver was ground‚ the bubbles from the reaction reached a maximum height of 150mm in five seconds less than the unground liver which merely reached a maximum height of

the rate of catalase activity The extent at which environmental factors affect the rate of catalase activity was discovered in this lab. The assay system‚ in which a filter paper disc was dipped into the enzyme and submerged using a stirring rod in a test tube filled with 20mL of hydrogen peroxide‚ was used to test several enzyme factors. As the saturation of hydrogen peroxide increased the rate of reaction increased as well. When the enzyme concentration increased the rate of catalase activity

of 1% hydrogen peroxide solution was made. In order to get this‚ the stock solution‚ which was 3%‚ was diluted using 10 mL of hydrogen peroxide and 20 mL of water. In the second beaker‚ a ¼ dilution of potato extract was made using 2 mL of potato extract and 6 mL of water. The third plastic beaker contained 8 mL of water. Using the first and second beaker the experimental assay was performed. Using forceps a small paper disk was dipped into the second beaker containing the potato catalase for

Abstract: Enzymes‚ molecules that speed up chemical reactions‚ are specific to one substrate. In this experiment the substrate hydrogen peroxide and the enzyme catalase will be used. The higher the concentration of potato extract‚ or catalase‚ the faster the reaction and the more substrate present will result in a decrease in the time of the reaction. The amount of concentrations of enzymes and substrates are changed to determine if the reaction is further catalyzed by a greater concentration of

Alcohol related liver diseases are a wide range area which refers to a general term named as alcoholic liver diseases. Millions of individuals around the world get affected with liver diseases due to high alcohol consumption. Several risk factors have been analysed that affects the risk of development and evolution of liver disease. The primitiveness and estimation of alcohol related alcoholic liver diseases depends on the pattern and term of alcohol consumption‚ presence of liver inflammation‚ diet

was the enzyme‚ catalase. An enzyme is a specialized protein which catalyzes reactions in cells. The enzyme in our experiment was catalase‚ which came from the potato juice. The function of an enzyme is to catalyze reactions in cells. The specific function of the enzyme in this experiment was to see if it affected the activity if it was exposed to different temperatures. A substrate is a material or substance which the enzyme acts. The substrate in our lab was hydrogen peroxide. Procedure

9:50am 2-26-2014 Dr Laynes Hypothesis: As the temperature of the enzyme catalase rises the activity of the reaction will decrease. Objectives: The objective is to compare catalase activity at different temperatures. Introduction Catalase speeds the breakdown of hydrogen peroxide. Catalase is present in every plant and animal organ. This is useful because hydrogen peroxide is harmful to cells. Temperature effects the enzyme effectiveness. Increase in temperature causes

From the graphs‚ it is evident that an increase in both catalase concentration and substrate concentration resulted in a higher rate of reaction or‚ as observed in the kPa graphs‚ a higher volume of O2(g) formed at the end of the 5 minute trial. Interestingly‚ it should also be noted‚ as it was mentioned in the Figure 2‚ that the trend for the 6mL of 3% H2O2(aq) was more of a linear trend than an exponential decay‚ steadily rising until the end of the 5 minute trial. From this‚ it can be inferred
