The table below shows what colour the solution has turned after Amylase solution and Benedict’s solution has been added to Starch solution at different temperatures. The tests were completed three times each temperature to find an average.
This graph resembles the results from the table above. Making it obvious to observe the unexpected results as the temperatures 2, 20 and 27 remained blue then 37 degrees changed to green and 60 degrees changed to orange.
This experiment was carried out to investigate how temperature has an affect on enzyme activity. This was done by preparing beakers with amylase, starch and benedicts solution at multiple temperatures and observing the colour changes present. The results collected from this experiment were

    INTRODUCTION: The objective of this lab is to measure the activity of an enzyme and the effects of environment conditions on enzyme activity. Enzymes are catalysts; agents that speed up chemical reactions by lowering the activation energy required. This means that a catalyst helps reactions occur at a greater speed and lower temperature.…

    Catalase 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.…

    In the cold scenarios, the molecules would be moving slowly, decreasing the chance of an enzyme-substrate interaction, and slowing down the enzyme’s processes. To extend this experiment, it is suggested to use 5℃ intervals, as well as going from -10℃ (below freezing) to 110℃ (above boiling). This would allow you to more accurately see the disparity between the hot and cold scenarios, and observe the effects of high temperature on photosynthetic and enzyme…

    Starch Experiment

    Analysis and Discussion The hypothesis that amylase would no longer hydrolyse the starch solution into maltose past 37°C was not supported by the data. Fig 1b, Fig 2.1 and Fig 2.2 all show the colour samples for various temperatures taken at increments of 10 seconds up to 40 seconds. Initially, 4°C was the slowest followed by 19°C then 37°C, 45°C, 80°C and 60°C being the fastest acting in the first 30 seconds. 80°C was the second-fastest acting temperature up until 20 seconds, but slowed down at the 30-second mark, allowing 37°C and 45°C to become higher ranked in the speed scale. This can be clearly seen at the 30 to 40 seconds increments on Fig 2.1 where the lines for 37°C and 45°C cross-over 80°C.…

    How To Increase The Rate Of The Breakdown Of Amylase

    Amylase is an enzyme in our saliva that helps us break down foods into sugar, amylase is a natural catalyst which speeds up a reaction. This enzyme interested us so we decided to test the rate of the breakdown of starch with amylase. This breakdown will be represented with a substance called iodine solution. Iodine solution is an indicator of starch, if there is any starch present the iodine solution will turn blue.…

    How Does The Temperature Of An Enzyme Affect The Rate Of Reaction

    Due to the fact that enzymes are proteins and have very specific amino acid structures, the components that alter the shape of the protein will also affect the function of an enzyme. Therefore as you increase the heat of a liquid solution you are also increasing the kinetic energy about the molecules, thus increasing the amount of molecular collisions. This elevates the rate of the reaction because there are more substrate and enzyme molecules impacting each other.…

    Hydrolysis Of Starch Essay

    This result was not promoted by past theoretical studies which addressed that even though α-Amylase is considered to still be active at temperatures slightly lower or higher than 37°C, the rate of this enzymatic reaction under this condition is still inhibited in some extent and hence inactivated, due to changes in the moving speed of molecules, the rate at which intermolecular collisions between enzyme’s active sites and their complementary substrates occur, and the amount of energy available for the reaction. The reaction rate of any enzymes, including α-Amylase, is directly proportional to the temperature before it reaches a certain limit. As the temperature reaches this limit (which was observed to be 37°C in this experiment) , causing the reaction to also be the speed up the most, it is high enough to denature the protein composition of the enzyme, resulting in the enzyme losing its initial shape and therefore the ability to bind securely to a specific substrate molecule, which is starch in this experiment, to degrade carbohydrate molecules contained in starch to small glucose-containing polymers such as maltose, maltotriose, α-1,4 linked maltooligosacharides, and α-limit dextrins. This was exemplified by the result as the temperature of the water bath was increased to 47°C, the overall average colour grades instantly dropped by 1.28 units from 7.2 to 5.92 units (Table…

    Potassium Persulfate Reaction Lab Report

    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.…

    Fungi And Temperature Essay

    Effect of temperature Temperature has a profound influence on the rate of all processes occurring in living organisms including fungi and it may determine the type of reproduction, the morphology of the organism and the nutrients required. For any particular organism, the minimum and maximum temperatures are the lowest and highest at which growth occurs, and the optimum is that at which the growth rate is the greatest. Majority of fungi are mesophylls and grow at moderate temperature. These values are called cardinal values. Temperature range of different enzymes are specific and it varies with different organisms.…
