Potato Enzyme Lab Report
I. Aim
The aim of the three experiments is actually to investigate the effects of different factors such as temperature, pH, and concentration of substrate, on the activity of the enzymes. By conducting these three separate experiments also, three graphs are able to be obtained where the trend of each factor affecting on the enzyme activity is shown and described clearly.
II. Hypothesis
Experiment 1 (Effect of Temperature):
As the temperature increases, the height of the bubble will increase too, indicating a faster rate of reaction.
Experiment 2 (Effect of pH):
Enzymes are affected by changes in pH. Extremely high or low pH values generally result in complete loss of activity for most enzymes.
Experiment 3 (Effect of Substrate Concentration): …show more content…

    Enzyme Activity Lab Report

    The optimum pH for the enzyme acid phosphatase was predicted to be within acidic regions and the results obtained showed that the optimum pH was about 5.5 see fig.10. It had the highest absorbance value, meaning it had the most PNP in the tube in the given time and thus the fastest rate of reaction. A change in pH changes the shape of the active site of the enzyme. The bonds within the active site of the enzymes are polar, this means that they are extremely sensitive to ions. The decrease in pH increases the concentration of H+ ions in the solutions, these interact with the polar bonds in the enzymes structure to form individual bonds. This disrupts the shape of the active site and thus the substrate PNPP is no longer complementary to the enzyme’s active site. So no Enzyme substrate complexes can be formed and the rate of reaction drops. The same thing happens when there are extra OH- ions in the mixture. The pH in our cells must be extremely specific and buffered in order to prevent changes in pH and the denaturing of these enzymes. The data collected during these experiments are very similar to those published and studied, meaning the results collected are valid, and thus the experiment…

    A change in pH disrupts an enzyme's shape and structure. When the pH changes an enzyme's structure, the enzyme can't do its job. Changes in pH break the delicate bonds that maintain an enzyme's shape. An enzyme will unravel, or denature, and become useless in a different…

    Finding the Optimal pH of the Enzyme Peroxidase with the Aid of a Spectrophotometer

    The peroxidase enzyme was partially purified, and the enzyme activity was calculated with the use of a spectrophotometer, demonstrating the effect of pH on peroxidase activity. The objective of this exercise was to determine the ideal pH for peroxidase activity. The data concluded that the optimum pH for peroxidase activity is 5, and the “standardized” enzyme volume is 2.8mL.…

    Lab Report Enzyme Lab

    Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature, pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions, which would otherwise progress more slowly.(Background Information; pg. 1) pH is a measurement of the acidity or alkalinity (base) of a solution. When the liver got mixed with H2O2 , the first time the chemical reaction was fast, the second time the reaction was slow and the last try was very fast. Temperature is the degree or intensity of heat present in a substance or object. When the temperature of the liver changed from freezing to very hot to room…

    This was conducted through four different experiments. The first tested the effect of temperature on enzyme activity. The independent variable in the first experiment was the temperature of the solution of pH 7 buffer, potato juice, and the enzyme. The independent variable for the second experiment was the pH of the phosphate buffer. The independent variable for the third experiment was the enzyme concentration of the solution, and finally the independent variable of the fourth experiment was the substrate concentration.…

    The liver that was at 25°C had a huge amount of bubbles (a 4 on the scale) and the 0°C still had some bubbles but not as much (a 2 on the scale). The boiled liver had no bubbles. My hypothesis was accurate, since the two colder livers showed a reaction unlike the boiled liver.…

    Enzyme catalysis was observed in order to analyze how changes in temperature, pH, enzyme concentration, and substrate concentration affected an enzyme-catalyzed reaction. This experiment analyzed the rate of enzyme-catalyzed reactions and observed the correlation between catalase activity and products formed. It was found out that the rate of an enzyme-catalyzed reaction starts off rapidly, decreases, and levels off or completely stops, and can be further affected by environmental factors, which play a crucial role in regulating enzymes and metabolic processes.…

    3-Amino-5-Nitrosalic Acid On The Reaction Rate Of Starch

    In the end, the concentration of simple sugars indicated the reaction rate, as time was controlled to four minutes. Enzymes function optimally at a specific range of pH, and most function at an optimal pH of around neutral, or 7. The results of this experiment indicate that the optimal pH may be around 7 to 8, not 7, as the reaction rate was the same at 7.2 and 7.9, and enzyme activity was decreased at pHs below 7.2.…

    The Part Played by Enzymes in the Functioning of Different Cells, Tissues and Organs

    Different sequence of amino acid produces different structure of protein, which determines the property of protein, thus each kind of enzymes has its unique active site, which only fits to complementary – shaped substrate to form product. Because of the feature of active site, each kind of enzymes therefore is specific for a particular reaction. However, there are several factors affect the rate of enzyme reactions, they are temperature, pH, concentration of enzyme, concentration of substrate and inhibitors. High temperature and pH affects the structure of enzyme, irreversible denaturation occurs, the shape of active site is changed, enzymes therefore no longer function. The effect of the other factors is slowing down the rate of enzyme reactions, it depends on the concentration of those factors. Since enzymes are catalyst of chemical reactions, they are responsible to the activities of cells, and they determine the function of tissues and organs as well.…
