LAB: Substrate Concentration Affecting the Rate of Enzyme Activity: Through the Experiment of Beef Liver Puree and Hydrogen Peroxide Research Question Does different amount of substrate affect the rate of enzyme activities? Purpose To examine how different types of concentration (Hydrogen Peroxide) affect the rate of enzyme activity. Hypothesis We believe that if there is more substrate concentrated‚ then there will be an increase in the rate of enzyme activity. This is because

In this lab we tested the effect of temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the difference absorbance levels they produced every 20 seconds for about 2 minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What we got from the experiment was at lower temperature we got very low numbers for the absorbance‚ which gave us a lower

Activity of the Enzyme Catalase in breaking down Hydrogen Peroxide and the effect of various factors on Enzyme Activity Introduction The enzyme catalase is present in cells in order to speed the breakdown of hydrogen peroxide (H2O2)‚ which is a toxic chemical to the human body. When hydrogen peroxide is broken down‚ the end products are Water (H2O) and Oxygen (O2). In this report‚ the reaction of catalase to hydrogen peroxide is being tested. Furthermore‚ the effects of temperature‚ concentration

Biomes Comparison Essay Ecologists group earth’s diverse environments into biomes. A biome is a complex of terrestrial communities that develops a large area and is characterized by certain soil climate conditions and particular assemblages of plants and animals. Not all species live in every biome they vary in their adaptations to different conditions. An adaptation is an inherited characteristic that increases an organism’s ability to survive and reproduce. These sorts of variations in plants

Title: Enzyme Activity Lab Purpose: To measure the rate of enzyme activity from a tissue abstract and experiment with different factors‚ such as the enzyme solution and the substrate with different hydrogen peroxide percentages and temperature‚ that affect enzyme activity. Hypothesis: 1) If the disk is placed into each beaker with 100 units/ml of enzyme solution‚ then the time for the disk to float will be 30 seconds. 2) If the temperature of the solution is at 5 degrees Celsius‚

experiment were to investigate the activity of enzymes‚ components that influence the enzyme’s activity‚ identify an unknown phosphatase‚ influence of inhibitors‚ and determine if inhibition is competitive or noncompetitive. A spectrophotometer evaluated the measurement of color change over a period time due to product being formed. Determining unknown phosphatase and effects from different inhibitors were determined by varying the pH and substrate concentrations. The unknown phosphatase analyzed showed

By conducting these three separate experiments also‚ three graphs are able to be obtained where the trend of each factor affecting on the enzyme activity is shown and described clearly. II. Hypothesis Experiment 1 (Effect of Temperature): As the temperature increases‚ the height of the bubble will increase too‚ indicating a faster rate of reaction. Experiment 2 (Effect of pH): Enzymes are affected by changes

Factors Affecting Enzyme Activity Abstract: In the following lab factors affecting enzyme activity‚ temperature‚ pH‚ enzyme concentration‚ substrate concentration and surface area will be tested on a beef liver enzyme to see if there will be any effect of performance. By doing 2 or more trials the results will show whether there is an effect to the enzyme from the following factors or not. Some of the factors may denature the enzyme and some will do nothing. Using a table qualitative and the
