Enzyme lab report Rating: 9,6/10 1005 reviews

An enzyme lab report is a document that describes the results of a laboratory experiment that investigates the properties and functions of enzymes. Enzymes are proteins that catalyze chemical reactions in living organisms, and they play a vital role in many biological processes. In this lab report, we will outline the purpose of the experiment, the methods used, the results obtained, and the conclusion drawn from the data.

The purpose of the enzyme lab report is to understand how enzymes work and how they are affected by different factors. Enzymes are sensitive to changes in temperature, pH, and the presence of inhibitors or activators. By studying the effects of these factors on enzyme activity, we can gain insight into the mechanisms of enzyme action and the role of enzymes in biological systems.

To conduct the experiment, we first collected a sample of the enzyme we wanted to study. This could be obtained from a variety of sources, such as plant or animal tissue, or it could be purchased from a supplier. Next, we prepared a series of reaction mixtures containing the enzyme and a substrate, which is the molecule that the enzyme acts upon. The reactions were carried out under various conditions, such as different temperatures or pH levels, and the rate of the reaction was measured.

The results of the enzyme lab report showed that the rate of the enzyme-catalyzed reaction was affected by the factors we tested. For example, we found that increasing the temperature or the pH of the reaction mixture caused the rate of the reaction to increase, while decreasing these factors had the opposite effect. Inhibitors or activators also affected the rate of the reaction, depending on their specific properties and the nature of the enzyme.

Based on these results, we can conclude that enzymes are highly sensitive to changes in their environment and that their activity can be modulated by various factors. This understanding is important for a variety of applications, including the development of drugs that target enzymes, the design of industrial processes that rely on enzymes, and the study of biological systems.

In conclusion, the enzyme lab report provides a detailed description of the results of an experiment that investigates the properties and functions of enzymes. By studying the effects of different factors on enzyme activity, we can gain insight into the mechanisms of enzyme action and the role of enzymes in biological systems. This understanding has numerous practical applications and is essential for advancing our knowledge of biology and biochemistry.

Because we were only able to stimulate an environment of a lower pH, we were only able to get 1 direction of slope, showing linear results. The amount will be the baseline for activities C and D. Multiple factors affect the activity of an enzyme 1. Add in 2mL of deionized water, 8 drops of catechol, and 8 drops of potato extract in all test tubes. . . A best fit line, along with its respective equation and R 2 value, is also given for all three temperatures to show the approximate constant amount of product produced over time for that given temperature.

The Use of Enzymes Lab Report Example

enzyme lab report

Most enzymes are very specific for a certain substrate, the active site on the enzyme molecule forms a "keyhole" into which the substrate fits like a key, the substrate molecule is then broken up into many smaller pieces. After adding H2SO4 for different time lashes, etc. Further temperature increases above this denature the enzyme; thus, the activity and rate decline. Activation energy is known as the energy required for a reaction to occur. If it is too hot or too cold, the runner may not run as fast as they could if it were, for example, 10 °C.

Our data shows a linear trend, however, research shows that the trend is in fact a parabola opening downwards with a maximum at a pH of 5, the acidity of Hydrogen Peroxide alone. When 10 drops were added it produced the darkest color value at 6 compared to at 0 drops the color was rated at a 1. Thus, showing that enzymes need to be in their optimal environments to work properly. Add 10 drops of potato extract and 1 of deionized water into each one. Denaturation is a structural change in a protein that alters its three-dimensional shape and causes the loss of its biological properties1. Results When the substrate of hydrogen peroxide was added to the substances each performed a vastly different reaction.

The effect of the other factors is slowing down the rate of enzyme reactions, it depends on the concentration of those factors. This, in turn, would slow the rate of the reaction as data shows. Also, it was found that the longer the enzyme was left in the water bath closest to its optimal temperature, the more product was produced as a result. . Approximately 2 grams of shitake mushroom were weighed out and placed into a mortar with 4 mL of extraction buffer 10 mM Tris.

Sucrase activity increases with increasing sucrose concentration Materials and Methods Effect of pH on Enzyme Activity 1. After the time is up record the color changes 1- for each tube in table 3. Discussion Catalase: Liver Substrate: Hydrogen Peroxide Looking at our data for the first experiment, we can infer that the liver contains the catalase enzyme while the hydrogen peroxide is the substrate. If a solution is too basic or too acidic in comparison to the enzymes optimum pH, the enzyme will begin to degrade until it eventually stops reacting all together. Toothpicks Controlled Enzyme 178 Words 1 Pages There were five different types of enzymes that were used to break down the toothpicks. Independent Variable temperature 3. This experiment will also show how molecules that work with the enzymes, otherwise known as substrates, speed up the chemical reaction.

Every …show more content… This also includes the measurement of the amount of Hypothesis: I believe with the inclusion of the enzyme catalase the reactions will begin to at a rapid pace but will eventually decrease with the addition of the hydrogen peroxide. Once the same amount of the substrate was added to the potato there was a slight fizzy and bubbly reaction thus earning the rating of 2. In experiment 2 the higher concentration of the substrate increases the activity of the enzyme. Enzymes work optimally in their specific pH which is usually 7. In order to start the reaction, reactants require an initial supply of energy called activation energy.

Enzymes are recyclable, and they have to do their job very efficiently, and if their shape is altered, this is no longer possible. In experiment 2 the hypothesis was proven to be right because it was thought that the more drops of the substrate used will increase the rate of the enzyme. A good comparison for the impact of temperature would be running. An example of an enzyme catalyzed reaction is enzymatic hydrolysis of an artificial substrate, o-Nitrophenylgalactoside ONPG used in place of lactose. The main pathway for yeasts is glycolysis which they use to catabolize their sugars. . Because the substrate already went through the chemical reaction, it could not go through another one with new catalase, but the old catalase still had functional enzymes and could therefore be reused.

The liver will have a large reaction because the majority of liver is proteins and enzymes which break down the Hydrogen Peroxide. Record the time taken by the filter paper to rise to the top by creating a data table on your paper. From the experiment, it is illustrated in the graph in figure 2 with the constant slope from the temperature of 40 C to 320 C. In this lab, the enzyme catalase was used to break down hydrogen peroxide into less toxic water and oxygen gas. The products produced can either be larger, or smaller than the original substrate, as the enzyme can either break down, or combine two substrates. The reactions were then carried out exactly as above, however, only at one temperature as the variable here is the concentration of cofactor or inhibitor.

Therefore, there may be an influence on the activity of enzyme which substrates cannot be binded on the active site if the amylase in too high or low ph and temperature and excess salt environment. . The effect of pH on the speed of enzyme interaction with substrate chemicals Hypothesis: About pH: If the pH level is less than 5, then the speed of the enzyme reaction will be slower. Catalase breaks down hydrogen peroxide, which is toxic, into 2 safe substances- water and oxygen, by speeding up a reaction. Then mix the catechol solution tubes into the potato extract tubes and place the tubes in the water bath for another 10 minutes.
