Effect Of Temperature On Amylase

Improved Essays
The control was the first row for both amylases. At 0 min. neither one had synthesized anything so this served as the starting point. The independent variable was the temperature; this is what was being changed. The dependent variable was the amylase activity; this is what (should have) changed because of the temperature. The iodine was a marker. It showed whether starch was still present in the wells. From the results, starch was present in all the wells; it was present at every temperature and every time interval. The hypothesis was not supported because temperature did not affect any of the amylase; there was no activity.
The results from the group experiment for Aspergillus oryzae amylase concluded with no changes taking place in any of

Amylase is an enzyme that breaks down starch. Among other factors, high temperatures denature enzymes. Through experimentation this was not observed. The results of the experiment resulted in flawed data. By human error, a mistake was made that affected how well the enzymes synthesized starch. Another possible factor that could have brought about the flawed results is a mistake in measurement, specifically in temperature. The goal was to have the optimal temperature present so that amylase for both bacteria and fungus could synthesize. If the temperature had been correct, then the results would have looked more like the expected results in Figures 4 and 5. This error was not limited to just this group, rather the majority of the class got these same flawed …show more content…
The errors made are something from which to learn from. Although the source of the error is not entirely clear, there are a few things that could have been done to prevent such a large margin of error. One could have been the accurate measurement of temperature for the water baths. They have to be representative of what will affect the enzyme accordingly. Another improvement would be the prevention of cross-contamination. A drop in the wrong place can skew the results. Human error is inevitable, but it is something from which to learn from. Although there was a large margin of error the results of this experiment conclude that the hypothesis is rejected. This experiment can be taken in other directions. There are other factors that affect enzymes, such pH and salinity. In what way would pH affect enzymes? Not only can optimal temperatures be explored for Bacillus licheniformis and Aspergillus oryzae amylase, but for other enzymes from other organisms as well. How would the optimal temperature for an enzyme from a human, a mammal (warm-blooded), compare to the optimal temperatures for an enzyme from a lizard, a reptile

    As the temperature increases, the rate of reaction increases until it has reached the optimum temperature above 37°C where the temperature is very high then the reaction rate will decrease. In the data table shown above, there is a similar pattern from increasing the temperature will increase the rate of reaction and as the temperature slowly increases to a certain point then the reaction rate will decrease. When the temperature increase above 37°C, then denature will occur. Also, the temperature increase, the kinetic energy where H2O2 molecules bind frequently with the catalyst increase the enzymes. Conclusions: An enzyme speeds up the chemical reaction, the activation energy allows energy to require to break bonds apart and lower activation…

    The hypothesis was proven wrong by the timing and values of the graph. I believe this was caused by the enzyme having to break apart a heightened amount of substrates in the mixed test tubes. This caused the initial data to yield a quicker reaction (on the basest of browning in color) compared to the altered data. The independent variable of this experiment was time, while the dependent variable was the color as the reaction is completely dependent on the duration of time. There were numerous potentially sources of error during this experiment.…

    The effect of altering temperature on the rate of liver enzyme activity is measured in this experiment to be able to visualize how temperature in the environment and in the body can manipulate the rate of enzyme activity. Enzymes are protein catalysts that lower the amount of activation energy required to start a biochemical reaction. According to Dr. Meyertholen (2015), enzymes are structured to work with certain substrates, meaning that the structure determines the function of the enzyme. If the enzymes shape is altered, they become denatured. Denaturation of an enzyme can occur with changes in factors such as temperature, pH, or salinity.…

    These amylases are to be tried at various temperatures fluctuating from 0° C to 80° C noted between 2 minute intervals until time extents to 10 minutes. This experiment will help define optimal temperatures of the bacterial amylase and the fungal amylase. It is predicted that at temperature of 55° C bacterial amylase will have its optimal temperature considering that bacteria number increases in warmer places. Furthermore, when the temperature is at 40° C, fungal amylase will have its optimal temperature considering that fungi thrive in cooler places. Additional matters to be attended in the following laboratory experiment are the denaturation of enzymes at a certain temperatures and enzyme activity as temperatures increase or decrease in relation to the optimal…

    The experiment began with a reaction of a 1cm3 cube of lamb liver and 5mL of hydrogen peroxide solution being put in test tubes in a beaker filled with 10℃ water until the temperatures of the liver and hydrogen peroxide were 10℃ also. The liver was put into a 100mL measuring cylinder and the hydrogen peroxide was also poured in as the timer was started. After twenty seconds, several millilitres of froth had been produced from the chemical concoction. This froth was recorded into a results table, and the previous steps were repeated but with increasing temperature increments of 10℃ until 50℃. After carefully completing the experiment, the final results obtained by measuring the volume of the froth produced after 20 seconds, were recorded in a table - see Table 1, and able to be observed in a graph, see Figure 7.…

    However, this was not the case in the experiment, meaning this part of the hypothesis is rejected. In fact, at a pH of 7, the enzyme activity has already begun to decrease. Rather, the optimal pH for enzyme activity was at a pH between 5 and 6. The first part of the hypothesis (that is pH affects enzymes) fails to reject because pH did affect enzyme…

    The purpose of conducting this experiment was to explore how different factors affect the reaction rate of enzymes reacting with their corresponding substrates in order to learn more about how enzymes function in different environments. The independent variables investigated in this experiment were the concentration of different substrates, the temperature of the environment, and the effect of a catalyst on the reaction rate. The dependent variable for all of the investigations was the time it took for the reaction to occur. To investigate the effect of the concentration of the substrate on the reaction time, four test tubes were used.…

    Abstract The purpose of this investigation is to determine whether the temperature can affect the reaction rate of enzyme activity. The enzyme activity was measured by five different temperatures, separated in tubes which later got measured by their height of foam after 10 minutes. Freshly-prepared potato juice was used as the enzyme for catalase. Since temperature is measured by the kinetic energy of molecules, the higher the temperature, the more movement of molecules.…
