...e substances at 37.5̊C due to the fact that in the previous experiment, this was found to be the optimum temperature that catalase reacts at. It was because of this constant that I used the set of data of the catalase at 37.5̊C from the first experiment to provide a neutral environment for the experiment. The way in which the data was collected for the first experiment was identical to that needed to be done by the second. From this data, it was determined that the neutral environment for the catalase had the best results, which makes it clear that when the enzyme is in a pH of the opposite extremes such as basic or acidic, it is un able to function properly. When it is too basic then the enzyme will become inactive and when the enzyme is too acidic then the enzyme will denature, both rendering it unable to function at its optimum efficiency that all enzymes need.

    Catalase is a common enzyme that is produced in all living organisms. All living organisms are made up of cells and within the cells, enzymes function to increase the rate of chemical reactions. Enzymes function to create the same reactions using a lower amount of energy. The reactions of catalase play an important role to life, for example, it breaks down hydrogen peroxide into oxygen and water. Our group developed an experiment to test the rate of reaction of catalase in whole carrots and pinto beans with various concentrations of hydrogen peroxide. Almost all enzymes are proteins and proteins are made up of amino acids. The areas within an enzyme speed up the chemical reactions which are known as the active sites, and are also where the

    The shape of the molecules is changing and so the enzyme molecules can no longer fit into the gaps in the substrate that they need to and therefore the enzymes have de – natured and can no longer function as they are supposed to and cannot do their job correctly. Changing the temperature: Five different temperatures could be investigated. Water baths were used to maintain a constant temperature. Water baths were set up at 40 degrees, 60 degrees and 80 degrees (Celsius). Room temperature investigations were also carried out (20 degrees).

    The Effect of Temperature on the Activity of the Enzyme Catalase Introduction: The catalase is added to hydrogen peroxide (H²0²), a vigorous reaction occurs and oxygen gas is evolved. This experiment investigates the effect of temperature on the rate at which the enzyme works by measuring the amount of oxygen evolved over a period of time. The experiment was carried out varying the temperature and recording the results. It was then repeated but we removed the catalase (potato) and added Lead Nitrate in its place, we again tested this experiment at two different temperatures and recorded the results. Once all the experiments were calculated, comparisons against two other groups were recorded.

    In this experiment as a whole, there were three individual experiments conducted, each with an individualized hypothesis. For the effect of temperature on enzyme activity, catalase activity will be decreased when catalase is exposed to temperatures greater than or less approximately 23 degrees Celsius. For the effect of enzyme concentration on enzyme activity, a concentration of greater or less than approximately 50% enzymes, the less active catalase will be. Lastly, the more the pH buffer deviates from a basic pH of 7, the less active catalase will be.

    The results of this experiment showed a specific pattern. As the temperature increased, the absorbance recorded by the spectrophotometer increased indicating that the activity of peroxidase enzyme has increased.At 4C the absorbance was low indicating a low peroxidase activity or reaction rate. At 23C the absorbance increased indicating an increase in peroxidase activity. At 32C the absorbance reached its maximum indicating that peroxidase activity reached its highest value and so 32 C could be considered as the optimum temperature of peroxidase enzyme. Yet as the temperature increased up to 60C, the absorbance decreased greatly indicating that peroxidase activity has decreased. This happened because at low temperature such as 4 C the kinetic energy of both enzyme and substrate molecules was low so they moved very slowly, collided less frequently and formed less enzyme-substrate complexes and so little or no products. Yet, at 23 C, as the temperature increased, enzyme and substrate molecules

    Catalase Activity Experiment Aim: to find out if different concentration of hydrogen peroxide release different amounts of oxygen when in contact with catalase enzyme. Risk assessment: Hydrogen peroxide is corrosive and can therefore irritate the skin and damage the eye if it comes into contact with these. To prevent this extra caution must be taken to avoid contact with the skin and goggles should be worn while carrying out the experiments. Other sharp implements such as the scalpel used for cutting the potato can be dangerous if the sharp side comes into contact with the skin as it could cut it. Prediction: I predict that as the concentration of the hydrogen peroxide decreases, so will the level of oxygen produced.
