The effect of various temperatures on Enzyme activity

Introduction: The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life's processes would not happen easily. An enzyme is a macromolecule serving as a catalyst, they are generally a protein based molecule, as it is in the lab, Enzymes are organic catalysts that control the rate of chemical reactions in cells while not being permanently changed or without being consumed, which makes enzymes different from other proteins. In general, enzymes speed up the rate of reactions by lowering the activation energy required to start reactions. Furthermore, Enzymes are extremely well organized. They can catalyze reactions at rates up to 10 billion times higher than non-catalyzed reactions. Due to their particular shape, they hold the reactant molecules in closeness and in the correct position for the reaction to …show more content…
Tube A, which was left in a cold temperature, had less fizzing (8.5cm); tube C produced medium amount of fizzing (10.5cm) and tube B had a greater fizzing which was 11cm. The result data that we collected after the experiment supported our hypothesis.
Catalase concentration: Upon adding the potato pieces to the test tubes while waiting to measure the production of O2, we noticed right away that tube A is not doing anything because its only contains hydrogen peroxide and not any enzyme catalase to start the reaction while tube B, which contained 1cm potato piece produced 7.7cm fizzing, tube C, which contained 2cm potato piece produced 8.5cm fizzing and tube C, that contained 4cm potato piece had a greater amount of O2 (11.5cm) in form of

    Yeast Optimum Temperature Lab Report

    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…

    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.…

    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 Effect Of Chemistry: Lab Analysis Of Yeast Catalase

    In this part of the lab, we pour 20 mL of Hydrogen Peroxide and 1 mL of yeast catalase in the reaction chamber and then submerge it in the water bath. After it was done, it can be concluded that the gas levels increased because when we first started timing it, the gas levels were at 76, but as time went by, the gas levels started to increase and in the end of the last interval, the gas level increased all the way up to 100. This result occurred because there were many active sites that were empty for the substrate to bind to and since they binded to the active sites, it started increasing a lot at the beginning. However, when the active sites started getting more occupied, the substrate could not bind to as much active sites, so the gas levels started to increase alittle less as time went on and in the end, there was no active sites that were…

    How Does Ph Affect Enzyme Activity

    For pH, it was hypothesized that the optimal pH would be 7. As temperature was increased, the enzyme activity also increased. Because temperature is the measure of kinetic energy, an increase in temperature would cause an increase in kinetic energy. This means that particles are moving quickly with high entropy, which causes more collisions to happen. Due to this, there is a higher probability of substrates colliding with enzymes, thus making the reaction occur.…

    Potassium Persulfate Reaction Lab Report

    In each tube, a certain amount of a starch solution and a potassium iodide solution was added. Then, each test tube was placed in three different baths, each with different temperatures: an ice water bath, a warm water bath, and a very warm water bath. After the solutions adjusted to the temperatures of the baths, they were taken out, and a certain amount of a potassium persulfate solution was added to each tube. After the potassium persulfate solution was added, the time it took for each reaction to occur was measured. For this experiment, the control variables were the amount of starch solution, the amount of potassium persulfate solution, the concentration of the substrate, and the absence of a…

    Catechol Enzyme Lab Report

    Discussion In this study, the Catechol enzyme was studied under the conditions of varying pH, temperature, substrate concentration, and enzyme concentration. In Figure 1, the data suggested that the trend was neither directly nor inversely proportional, but the highest activity rate was at 24°C. Most enzymes denatured at higher temperatures of approximately 40°C, which led to the inability to see any color change (Helms et al., 1998). At lower temperatures, the enzyme was somewhat efficient because molecules move slower at lower temperatures, so enzymes lost productivity.…

    The prediction for this experiment was: when the temperature hits 80 degrees Celsius, the catechol will be at its optimal absorbance. The alternate hypothesis tested for this following experiment was that there is a significant relationship between catechol and pH. In contrast, the null hypothesis states that there is no significant relationship between catechol and oxidase and pH. This hypothesis will be supported if the rate of catechol oxidase does not increase. The hypothesis was tested by observing the reaction time of catechol oxidase at four different…
