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. Class practical or demonstration hydrogen peroxide (h2o2) is a by-product of respiration and is made in all living cells hydrogen peroxide is harmful and must be removed as soon as it is produced in the cell cells make the enzyme catalase to remove hydrogen peroxide. Investigating the effect of substrate concentration on catalase reaction - investigating the effect of substrate concentration on catalase reaction planning -aim: the aim of the experiment is to examine how the concentration of the substrate (hydrogen peroxide, h2o2) affects the rate of reaction of the enzyme (catalase.
This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase introduction this is an a-level biology project.
4 repeat the experiment with hydrogen peroxide concentrations of 16%, 12%, 10%, 8%, 4% and 0% the 0% concentration of hydrogen peroxide solution is done as a control solution to show that at 0% concentration no reaction occurs. In this given experiment, it was to be tested what impact the concentration level of substrate will have on the reaction rate the enzyme catalase, found in potato juice, was used for the catalyst along with a substrate known as hydrogen peroxide (h2o2. Substrate concentration and yeast catalase aim: to see how the substrate concentration in hydrogen peroxide affects the rate of an enzyme controlled reaction using yeast catalase introduction: an enzyme is a biological catalyst made of protein. Cells make the enzyme catalase to remove hydrogen peroxide this investigation looks at the rate of oxygen production by the catalase in pureed potato as the concentration of hydrogen peroxide varies the oxygen produced in 30 seconds is collected over water.
The substrate in use will be hydrogen peroxide and we will be testing to find out how increasing the concentration of this will affect its reaction with the enzyme factors affecting the investigation: â concentration of the substrate. This experiment looked at how substrate concentration can affect enzyme activity in this case the substrate was hydrogen peroxide and the enzyme was catalase pieces of meat providing the catalase were added to increasing concentrations of hydrogen peroxide in order to measure the effect of hydrogen peroxide concentrations on the enzyme’s activity.
Catalase does not react because these are not the proper substrate for the enzyme temperatures of chemical reactions cold temps slow chemical reactions while warm temps speed chemical reactions. This is because as there are progressively fewer molecules of hydrogen peroxide there will be fewer collisions between the substrate and enzyme molecules (catalase in yeast), leading to a decrease in enzyme-substrate complexes formed. The enzyme catalase, found in potato juice, was used for the catalyst along with a substrate known as hydrogen peroxide (h2o2) the job of catalase in this experiment was to accelerate the breakdown of hydrogen peroxide into water and oxygen gas. On the enzyme catalase stephen francis biology 183 abstract this experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide.
