concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of catalysis such as an enzyme. Moreover to increase the effectiveness of an enzyme one must add additional amount of enzyme due to saturation. Therefore the 100% will have the greatest effect because is has the highest concentration of the catalase.

Premium Enzyme Catalase Catalysis
Catalysis is an enzyme that decomposes hydrogen peroxide into oxygen and water. In this lab we will conduct a series of experiments to determine the affects of; pH‚ temperature‚ and concentration change on such catalysis. After completing the experiments we determined that catalase works most efficiently when in a 27°c‚ 50% (5 ml of catalase – 5ml of water)‚ and a normal body pH of 7°.

This practical was designed to investigate the effects of temperature on reactions between the enzyme catalase found in animal tissue with the substrate H2O2. The hypothesis stated that an increase in the temperature of the substrate would create a subsequent increase in the rate of reaction between the enzyme and the substrate. This hypothesis was tested by immersing 1cm cubes of animal tissue (sheep liver) which contained the enzyme catalase into the substrate (H2O2 ) mixed with detergent which foamed

The Effect of pH on the Rate of Enzyme Catalysis of Catalase Objectives: The objective of this lab was to develop a protocol to investigate the effect of an environmental variable on the catalytic function of an enzyme. More specifically‚ the objective was to perform an experiment in order to test the effect of pH on the function of the enzyme catalase. Introduction: Enzymes are proteins that act as catalysts for reactions. This simply means that enzymes lower the activation energy required

it down the cell will die‚ along with the organism itself. However with the aid of an enzyme‚ catalase‚ hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver‚ a vegetable‚ and breast tissue. By using variables such a pH and temperature we are able to how the rate of reaction is altered or improved. If it has improved‚ the optimum

hydrogen peroxide By Cuong Tran Abstract: The purpose of this investigation was to determine the optimum temperature for enzyme activity. The stated hypothesis was that 37oC would be the optimum temperature for liver enzymes to break down hydrogen peroxide into water and oxygen. The dependent variable was to measure the amount of foam being produced‚ while testing 4 different temperatures with 3 repetitions each. Out of the 12 trials only 2 outliers were found and an inclusive overlook of random

affect the temperature of maggot mass and development of maggots in the mass? Abstract The aim of this investigation is to find a correlation between the number of maggots in the mass and the temperature of maggot mass. To find the correlation the different number of maggots in each mass was placed in (the isolated by glass beakers) polystyrene cups. The internal temperature of masses was obtained regularly every 10 minutes during 30 minutes time period under the same temperature of surroundings
