Enzymes
Two major factors influence how effective an enzyme is by promoting the rate of reaction. Each enzyme has a specific temperature that allows it to perform the most work. If an enzyme is placed in an environment under its optimal functioning temperature, the speed of the reaction will slow. Reason being, the molecules of the reactants reduce in energy from the low temperature, less movement means less reactions with the enzymes. At higher temperatures, molecules within an enzyme increase in rate. The hydrogen atoms within the protein bonds disconnect, causing the protein to lose its shape. Thus it ability to intake substrates.
Ph plays an important role in the enzyme rate of production due to it’s ability to alter electric charges. If Ph is too high or too

Because of the enzymes reacting less frequently with substrate molecules at 22°C, larger molecules of Casein will still be present. As a result, the absorbance will be higher from light passing between the molecules. Continuing on, Temperature 22°C will have more absorbance than 32°C because we are moving closer to the enzymes optimal working temperature. For our upcoming experiment, the Trypsin will work best at 37°C as stated above. At 37°C, the level of absorbance will be the lowest because the enzymes will be working at the best rate to break down Casein. For that reason, the broken down substrate will dilute the solution, not allowing light to pass through. At 42°C, the absorbance will increase slightly. Enzymes at 42°C are still closely maintaining its structure, but minimal changes to the active sight, make it more difficult for the substrate to connect. At 52°C, all bonds within the enzyme will be altered or broke, eliminating any possibility of reactions. Substrates will not be broken down at 52°C, so it should have the highest absorbance

    By adding more temperatures, the results become more precise as to what temperature amylase denatures at, and what temperature is the most efficient for amylase. Variations that differ from the variables in this experiment could be the effect of pH levels on enzyme activity, which would show the best pH levels for amylase to be most efficient and whether it works best at low, medium or high pH levels. The concentration of amylase would also be a variation that would show whether amylase works faster if there is more of it or not. If all of these variations were done, it would show in what conditions amylase works best at, and if the human body fits those conditions or…

    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.…

    When high temperatures are reach the hydrogen bonds break and the 3D shape is changed. When boiling the enzyme or extract, such high temperature result in a permanent change in the structure of the protein called denaturation (Dolphin, 2015). Competitive inhibitors can affect how easily the substrate can bind to the enzyme. Hypothesis for effect of temperature: As the temperatures increase the enzyme and substrate will collide at a faster rate causing the hydrogen bonds to break and the shape of the enzyme to change. Hypothesis for effect of pH: The enzyme reaction rate of binding to the substrate will favor a more neutral pH value so that the shape of the enzyme is not altered.…

    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.…

    From 10oC to 20oC, the average rate of reaction of the class results is higher than the raw results rate of reaction by a maximum of 0.75mL/sec. However, from 30oC to 50oC, the raw results presented a slightly higher lot of rate of reaction than the average rate of reaction from the class results. The highest rate of reaction difference was for 50oC, with a difference of 0.3mL/sec between the raw and average results. This information supports the hypothesis, yet the result for 10oC and 20oC do not support the hypothesis, as due to the information known about enzymes, the lower the temperature, the slower the rate of reaction should be, therefore the average rate of reaction does not support the…

    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…

    The goal of this experiment was to determine the Michaelis constant (Km) and also the maximal velocity (Vmax) and the inhibition of alkaline phosphate. In order to accomplish these goals, 5 samples were used. Each sample contained different volumes of 0.2 m MPNPP (p-nitrophenylphosphate) and 0.2 M Tris-Hcl at a pH of 8.0. To each sample 0.2 mL of the enzyme studied (Alkaline Phosphatase) were added upon insertion on the spectrophotometer apparatus. With intervals of 20 seconds their absorbance at a wavelength of 410 nm was recorded at time frame of 2 minutes for each solution.…

    The pH range in which an enzyme will remain functional is limited. Within this range there is an optimal pH at which enzyme activity is at its peak. Changes in pH affect the protonation state of an enzyme’s functional groups, altering the intra and intermolecular bonds responsible for the secondary and tertiary structure. This may result in decreased function due to changes at the active site lowering substrate affinity, or full deactivation caused by denaturation (unfolding of the protein).…

    The average absorbance rate in figure 2 presents the different levels of reaction in terms of the chemical compounds. Comparing the average values (Team 1 representing our results) there is not much of a pattern when viewing the absorbance for each specific test tube for each team. Although, there are some values that were around the same range including test tube 2. As for enzyme change, the high amount of enzymes increases the absorbance that shows an increase in reaction as seen in test tube 4 (figure 1). However, because of the decrease at 30 minutes the results take a shift.…
