Recommended: Investigating catalase activity

1. The reaction is an oxidation and reduction reaction. Bubbles were observed because oxygen is being release from the reaction as a gas as part of the reduction part of the reaction. Enzymes work efficiently at a body temperature of 37o C therefore if the enzyme was boiled before adding it to the peroxide there would be no bubbles due to the fact that the enzyme would be denatured. The enzyme would be inactivated.
2. The catalase which is the enzyme breaks down the substrate hydrogen peroxide forming the product water and oxygen. There is less hydrogen peroxide concentration as time is increased due to break down of the substrate. As time is increased more oxygen is given off, more water is formed resulting in a decrease in color intensity. …show more content…

Catalase acts by breaking down hydrogen peroxide and producing water and oxygen. Glucose oxidase then acts by converting glucose sugar into gluconic acid the reaction then utilizes the oxygen released from hydrogen peroxide

4. Catalase is used in the textile industry:
Catalase is used to decompose hydrogen peroxide and produce water and oxygen. Catalase is introduced in the dyebath before adding dyes and chemicals to remove hydrogen peroxide. Catalase is effective as it neutralizes before the dye is added to the textiles. Catalase is effective in a pH of 6-8. The advantages of using catalase is that shortens the process duration, improves productivity, decrease the amount of water required and saves energy (Zhang, Du and Chen, 2010).

5. Catalase is used in the papermaking industry:
The catalase is made up of Aspergillus niger, the catalase works by removing the excess hydrogen peroxide after the bleaching process. It works by breaking down hydrogen peroxide and producing water and oxygen. The use of catalase shortens the process time, saves energy and reduces pollution. Used as an alternative method due to that fact that it produces cleaner products. Catalase can also be used in the paper making industry to soften wood pieces. (Jegannathan and Nielsen,

Catalase Activity on Substrate Based On Gas Pressure Production Rate Name of the Class Author’s Name Date Enzymes are organic compounds which act as catalysts and speed up biological reactions in biological organisms. They are not destroyed or changed during the reaction but rather they are used over and over again to catalyze many more reactions. Their activity may be affected and altered by factors such as temperature, substrate concentration, enzyme concentration and Ph.

Enzymes are a form of protein that lowers activation energy and speeds up reactions as a catalyst. They are made by the stringing together of an abundant amount of amino acids and folded into a specific shape for chemical reactions. Turnip Peroxidase is the enzyme used in this lab and is derived from the vegetable. Enzymes are not used up or permanently altered by their environment Peroxidases are found in a range of organisms and function to break down alcohol (H2O2) and creates byproducts of oxygen and water. In this experiment, the reducing agent guaiacol is added with the substrate, hydrogen peroxide, to create water and oxygen.

In cycle one, the double displacement reaction, Cu(s) + 4HNO3(aq) → Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) occurred, the result of the reaction was that the reaction mixture began to bubble with the copper filling dissolving and a vapor like substance leaving the reaction. Furthermore, when water was added, the color change, from brown to a blue color pigment. Then in Cycle two, another double displacement reaction occurred, Cu(NO3)2(aq) + 2NaOH(aq) → Cu(OH)2(s) + 2NaNO3(aq), which resulted in the reaction becoming cloudy and a darker shade of blue. Following cycle two, a decomposition reaction occurred as the result of heat being administered to the mixture, thus the following reaction occurred in cycle three, Cu(OH)2(s) → CuO(s) + H2O(l). As a

1 “substrate” and another “ enzyme.” Instead of using the distilled water, this time you are going to use different pH buffer in the enzyme test tube. In the substrate tube, add 7 mL of distilled water, 0.3 mL of hydrogen peroxide, and 0.2 mL of guaiacol for a total volume of 7.5 mL. For the enzyme tube, instead of distilled water add the pH solution (3) and 1.5 mL of peroxidase which equals a total volume of 7.5 mL. Use the dH2O syringe for our pH solution. To clean the syringe, flush it by drawing 6 mL of distilled water.

The disks rises to the top of the cup because the substrate, hydrogen peroxide, when sped up by enzyme, creates both water and oxygen as products. The released oxygen is attached onto the disks, allowing it to float to the top of the cup. The way the concentration of enzyme affect the rate of the reaction is because more concentration of enzyme the more active sites are present for the substrate to chemically react with.

ABSTRACT To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. In this experiment we examined how increasing the volume of the extract added to the reaction would affect the rate of the reaction. The enzyme used was horseradish peroxidase which helps catalyze hydrogen peroxide. Using different pH levels, the absorbance rate of the reaction was measured to see at which condition the enzyme worked best. The rates of absorption were calculated using a spectrophotometer in 20 second intervals up to 120 seconds.

Enzymes speed up chemical reactions enabling more products to be formed within a shorter span of time. Enzymes are fragile and easily disrupted by heat or other mild treatment. Studying the effect of temperature and substrate concentration on enzyme concentration allows better understanding of optimum conditions which enzymes can function. An example of an enzyme catalyzed reaction is enzymatic hydrolysis of an artificial substrate, o-Nitrophenylgalactoside (ONPG) used in place of lactose. Upon hydrolysis by B-galactosidase, a yellow colored compound o-Nitrophenol (ONP) is formed.

These factors include the pH and the temperature of the solution (1). Most enzymes have a preferred temperature and pH range (2). The preferred temperature for catalase falls between the ranges of thirty five to fifty degrees Celsius (4). Temperatures that are too high denature the enzyme and halt the enzyme’s activity (2). Catalase denatures starts to denature at fifty five degrees Celsius (2).

Introduction In class, a series of experiments were performed that pertained to the enzyme known as catalase, which converts hydrogen peroxide into oxygen. Due to peroxide being toxic to the tissues of both plants and animals, both possess the enzyme catalase, which breaks into two non-toxic compounds: water and oxygen gas. Enzymes are proteins that react to certain substrates to create a product, and continue doing so afterwards. Methods and Materials To test reactions between catalase and hydrogen peroxide, groups of three to four people were formed.
