About this resource This Science essay was submitted to us by a student in order to help you with your studies. For a reaction to occur there must be successful collisions in which: For a given enzyme concentration and high concentration of substrate, the rate of product formation becomes independent of substrate concentration and reaches a maximum velocity known as: Record the quantity of oxygen evolved and during a standard time.
Record the quantity of oxygen evolved in each reaction. Enzymes are biological catalysts - Investigate the effect of temperature on the activity of catalase Essay introduction.

Also, if available lab coats will also be worn. An intensive metabolic activity can be found in soaked pea seeds as they begin to germinate.
When a small quantity of hydrogen peroxide is added to it, the enzyme Catalase present in the soaked pea seeds breaks down them into water and oxygen, producing froth due to the release of oxygen gas.
This is a region, normally a depression or cleft, to which another molecule may bind. A stopwatch or any similar device can be used to monitor the time of reaction.
Without Catalase, Hydrogen Peroxide accumulates in the liver and effectively dissolves the organ. The following table shows the standard deviation of the different sets of trials. Normally, hydrogen peroxide decomposes to form hydrogen and oxygen: Crush suitable quantity of pea seeds that will give the standard low concentration of hydrogen peroxide as used in the pilot study, into a coarse powder and load same quantity of the powder into 6 different test tubes closed test tubes by crushing more pea seeds as many times as the no.
Individual students may then have time to gather repeat data. For others it is necessary to supply energy in order to start the reaction.
Method of changing the independent variable 1. This is called the transition state. Calculating the Average As can be seen in the above table, for each set of 5 trials with a different amount of hydrogen peroxide used there were 5 separate, and usually similar results.
Put them both into the beaker of water once the water has reached the desired temperature this can be done by heating or adding ice to water. Once the bonds have been broken, the enzyme is said to have become denatured.
For a given [E]0 and low values of [S]0, the rate of product formation is proportional to [S]0. This is because there is more surface area which is exposed. For a given [E]0 and high values of [S]0, the rate of product formation becomes independent of [S]0, reaching a maximum value known as the maximum velocity, V max.
Method of measuring dependant variable 1. The reaction is exothermic. Essay UK - http: The oxygen formed reacts with the enzymes active site and displaces the water that has formed there from the above reaction. Record the concentration and quantity of hydrogen peroxide used in each reaction.
The steadily raising line in the beginning of the curve plotted represents the increased rate of catalysis by the enzyme Catalase. A stopwatch or any similar device can be used to monitor the time of reaction.
Is my conclusion valid? The test tubes used must be of sealed type with a provision for inserting the probe of a suitable oxygen detector into it. Some energy releasing reactions in cells produce hydrogen peroxide. This breaks the double bond between the hydrogen heterolytically.Investigation: enzyme activity - Sample Essay To investigate how the concentration of hydrogen peroxide effects the rate of reaction of an enzyme (catalase) Variables: These factors could effect the rate of reaction on an enzyme: pH Concentration Temperature Surface Area pH – Enzymes function at different pH values.
The aim of this experiment is to find out the effect of temperature on catalase or hydrogen peroxide. This will enable us to tell at what temperature hydrogen peroxide is most efficient. Catalase Investigation Essay - Catalase Investigation Introduction This investigation aims to determine the effect that varying the pH of the conditions in which a reaction between an enzyme and a substrate takes place.
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 oxygen produced in 30 seconds is collected over water.
The rate at which the reactions will occur will depend on how many enzymes molecules are present and the speed at which enzymes can convert the substrate into product, release it and bind with another substrate molecule/5(8).
