enzyme report
In this lab we used a solution of lactase to test the chemical and physiological properties of this particular enzyme and determined whether the lactase came from human cells or bacterial cells. In the statistical analysis statistical formulas and techniques are used to analyze the significance of a set of data and the validity of the conclusions made based on that data. These are some terms and definitions that will be crucial to understanding the validity of this experiment. An enzyme is a protein that acts as a catalyst to lower the activation energy required for reactions to progress in the cells. Null hypothesis states that there will be no difference between the result of two separate variables A and B. The null hypothesis states in regards to the enzyme experiment that lactase will not bind preferentially, or more specifically, to maltose or lactose. Before a null hypothesis can be rejected we must notice a large difference between glucose produced from maltose versus lactose. Alternate Hypothesis states the opposite of null in that there will be differences between the results of A and B. Probability is an indication of likelihood very similar to a percent chance. All probabilities are between 0 and 1, with probability zero indicating an event is impossible and one indicating an event is certain to occur. T-value or t-Test is what is used to determine whether or not the null hypothesis is valid. This t-value can be used to create a p value which in turn will determine whether the results are statistically significant or not. Based on what I know about the effect of temperature on the enzymatic activity of lactase, I hypothesize that higher temperatures will cause denaturing in the enzyme causing it to be less effective and lower temperatures will more conducive to enzymatic activity, and a higher pH will be more conducive to enzymatic activity.

    The results of our experiment showed the solutions in both tube 1 and tube 2 increasing in absorbency in the first eight minutes but then tube 1 continued to increase while tube 2 began to balance out. Tube 3, our blank, managed to stay at 0nm the entire twenty minutes. From this data, we can conclude that our hypothesis was supported that EDTA had a greater change in absorption over PTU.…

    The prediction for the effects of temperature on the enzyme activity was that the reaction’s rate would increase as the temperature increased, until they go over the optimum temperature where the enzymes denature and the reaction’s rate quickly drops to zero. At 5 degree C the rate is 0.00059mole PNP/min. This then increases to 0.01031mmoles PNP/min at a temperature of 50 degree C. The rate then drops drastically to -0.00215moles PNP/min. This point is where the enzymes have been denatured and have no activity, shown as the last point on the fig 8 and 9, do not fit on the graph. The optimum temperature was about 47 degree C. The core body temperature is only about 37 degree C and thus these enzymes are operating below their optimum temperature.…

    After placing 10 drops of hydrogen peroxide and vinegar substrate in the different forms of avocado, the results were interesting. The ground and reused enzyme had the most evident reactions. It also shows me that enzymes can be reused, because of the reaction rating. Enzymes can be affected by temperatures because the regular enzyme reaction is low. Also enzymes aren’t affected by pH because it had a low reaction. Enzymes are specific because different types of enzymes work for different substrates.…

    Our experiment looked at how increasing the surface area of a substance affects the amount of bubbles created due to the presence of the enzyme catalase. The experiment used two pieces of fish, one whole and one ground up, which were then covered in hydrogen peroxide. This method allowed us to observe the catalase in ground up fish break down the hydrogen peroxide at a quicker rate than in the piece of fish left intact. This was determined by observing a larger formation of bubbles, the visual indicator of hydrogen peroxide being broken down into a non-toxic form of hydrogen and water. This study allowed us to observe first hand catalase can perform further when the surface area is larger.…

    Enzymes are proteins that are involved in all the chemical processes in living things. As they are made of proteins they are affected by pH and temperature. Enzymes are catalysts; they speed up chemical reactions without being changed themselves. Digestive enzymes speed up the breakdown of large food molecules into smaller ones so that the blood can absorb them. Enzymes turn a large starch molecule into thousands of tiny glucose molecules. Enzymes end in 'ase'. There are thousands of enzymes in our body but each enzyme is only specialised to do one thing, for example carbohydraise enzymes digest carbohydrates, protease enzymes digest protein.…

    This lab allowed us to study chemical reactions and how catalysts will affect the rate of these reactions. The reaction we studied is the breakdown of hydrogen peroxide to water and oxygen and it is vital to life. The molecule hydrogen peroxide is a molecule that is toxic to cells but is also a by product of various cellular activities. (Lab Manual) The breakdown of these molecules to water and oxygen is a slow process. However, the breakdown of hydrogen peroxide inside the cell happens very quickly. This breakdown within the cell happens so quickly because of an enzyme called catalase. Catalase is produced in most cells of the body and the breakdown of hydrogen peroxide can occur with a smaller amount of energy when this enzyme is present. For this lab, we used catalase from beef. In order for chemical reactions to occur they have to be given enough time or extra energy in the form of heat, or both. By adding a catalyst to the reactants, the reactions, can be sped up or may require less energy input. A catalyst is a “chemical agent that selectively increases the rate of a reaction without being consumed by the reaction”. (Campbell p.152) Catalysts may be reused several times. The reason we use a catalyst is to lower the energy of activation of the reaction. Energy of activation is defined as “the energy required to get the reactions started”. (Lab Manual) Metabolism in living organisms must be conducted quickly and at temperatures low enough to prevent the organism from dying. Using organic catalysts, such as enzymes (protein-based molecules), allows this to occur. Each enzyme in living organisms is specific to a particular kind of reaction and without these enzymes; critical reactions could not take place because they would cause severe…
