How To Write An Enzyme Lab Report

Introduction

The topic of the lab was to introduce the basics of enzymes. The topic is important because they are in every living cell and because of enzymes chemistry is allowed in the cell. They do this by providing the energy needed for chemical bonds to break down and lets molecules interact with each other. For part 1 of the lab my hypothesis was if you increase the concentration, then the absorbance will also increase. For part 2 section A my hypothesis was if you increase the temperature, then the enzyme reaction time will also increase. For part 2 section B my hypothesis was if we change the level of the pH, then the ability of the enzyme will be changed. In part 2 section C my hypothesis was if you increase the concentration,

First for this experiment start by getting one Lactaid pill and crush it into powder with a mortar and pestle. Then add powder to 5 mL of phosphate buffer and vortex to dissolve the pill. Put 1 mL of the solution into 5 of the microcentrifuge tubes and 1 mL of water in a microcentrifuge tube and centrifuged these tubes for 5 minutes. Then combine the solutions into one clean test tube and put it ice. Next combine 3.5 mL of buffer and 0.5 of your substrate. Then obtain 0.5 sodium carbonate, which was the stop solution. Next add 0.5 mL of enzyme to the buffer and substrate and start the timer. Wait until a pale yellow color appears to add the stop solution and also stop the timer. Then determine the absorbance by using the Spec 20 and recorded the data. The control for this experiment was the amount of enzyme solution that was …show more content…
When given an unknown solution you can use Excel and determine the concentration or absorbance and determine what the substance is. The results in part two shows that temperature, pH,and concentration can affect enzyme activity. This means the environment has a key role in if the enzyme activity will decrease or increase. Every enzyme assay we did was wrong due to the fact we did not ice our solution long enough. Improvements for this would be to come around to every group and make sure the students are doing

    Add 5 cm3 of amylase enzyme into other 5 labeled test tubes. Put one of the starch solution test tube (preferably the one labeled 1) and one of the test tube containing amylase into the water bath (10 °C). Do the same for the other test tubes. Let the test tubes not be disturbed for 3- 4 mins. Then add the Amylase solution to the Starch solution and start the stopwatch (immediately).…

    Incubate the bottles for 5 minutes. Swirl the bottle around to make sure that trypsin removes all the cells from the bottle. Then, use a pipette to remove the substrate from the bottles and into centrifuge tubes. Then centrifuge the tubes for 1 minute at 1000xg. Make sure that the centrifuge tubes are properly balanced.…

    After the initial temperature was recorded the MgO was quickly added and the cup was swirled while the temperature changes were recorded. After the data collection as over the reaction stopped the reaming MgO residue on the watch glass was recorded and all waste products were disposed of and all material were cleaned. The data form reaction four was saved on the lab quest so that reaction five could be carried out. The Styrofoam cups were restacked and placed in a 400 mL beaker to which 120 mL of 2M HCl was then added the calorimeter was then closed and the initial temperature was recorded by using the lab quest. 0.5 g of Mg was then gathered and weighed using the scale and watch glass, all weights were recorded in table 3.…

    First, we will observe if a change in enzyme concentration affects the rate at which an enzyme reacts. Here, one may expect a high concentration in enzyme activity to result in an increase of enzyme reaction. Thus, leading to an increase in the absorption of the extract being used. Second, we will examine to see if a change in pH causes a change in the absorbance rate. Normally, absorption rates are higher at the pHs of around 5 to 7.…

    In this case, we were able to prove that chymotrypsin works ideally at pH range between 7 and 8. As can be seen from graph 3 the rate clearly undergoes a rapid rise around pH 7 and continues to the max at pH 8. This increase in reaction rate can be accredited to the specific qualities of the acyl-enzyme intermediate and the reaction environment required to allow the steady state deacylation to proceed. This can be explained by examining the catalytic triad of chymotrypsin, mentioned earlier, and its importance in the activity of the enzyme. In particular we can examine the histidine residue of the triad, which in the second step is responsible for being protonated by water which ultimately results in the release of acetate from the serine residue resulting in a free enzyme that is able to react with a new substrate.…

    The beaker was stir on the stirring plate until the solution dissolved completely. The already calibrated pH meter was used to measure he initial pH of the buffer as 10.40. HCl was added drop by drop in order to lower the pH to the desired 6.8. A final pH of 6.62 was achieved. Once the buffer was ready, 5 ml of it were added with the graduated cylinder to the initial beaker with the stacking gel.…

    A solution of .25 M HCl was first prepared by placing 25 mL of .5 M HCl in 25 mL of deionized water. The burette was then reconditioned with two 10 mL portions of deionized water and tow 5 mL portions of HCl. The burette was then filled to the 25 mL mark. A volumetric pipette was then sued to transfer 10 mL of acetic acid buffer to 50 mL of deionized water and the beaker was then placed below the burette. The pH probe was then rinsed and placed in the buffer solution to obtain an original pH reading.…
