Aim Of Enzyme Catalase Lab Report
1.Introduction: An enzyme is a large protein that acts as a biological catalyst which changes the rate of a reaction. It provides an active site which is an environment where a reaction can take place this is made up of amino acids. The structure and shape of the substrate, the structure and shape of an enzyme and the substance upon which the enzyme works all have to match exactly. This enables the substrate to bind, but it can 't do this if the shapes of the two are different. The Aim of Enzyme Catalase Experiment is making a series of experiments involving the enzyme Catalase which has been performed in order to determine some of the enzyme 's properties. The enzyme found in different conditions which its specific reaction rate. Variation in enzyme concentration, variation in pH, variation in temperature, and the effect of different concentrations of inhibitors were all tested. The enzyme concentration increased the reaction rate. An optimum pH and temperature were found for the enzyme, outside of this optimum the reaction rate would be lower. The correct name is the catalase enzyme. The EC number is: EC 1.11.1.6 . The biological function of the enzyme is catalyzing the decomposition of hydrogen peroxide to water and oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). Likewise, catalase has one of the highest turnover numbers of all enzymes ,one catalase molecule can convert approximately 5 million

1410 Words | 6 PagesCatalase 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.

740 Words | 3 PagesTitle: Enzymes Abstract: Enzymes can catalyze chemical reactions by speeding up the chemicals activation energy. Temperature and pH are just two of the factors that affects enzymes and their involvement with chemicals and the way they function. Throughout this experiment, we conducted a study on peroxidase, which is an enzyme. The following information consist of the recordings of when it was exposed to four different pH levels to come up with an optimum pH and IRV at the end. Introduction: Enzymes are proteins that are used in reactions in living organisms.

Enzyme Lab
901 Words | 4 PagesIntroduction: Enzymes are needed for survival in any living system and they control cellular reactions. Enzymes speed up chemical reactions by lowering the energy needed for molecules to begin reacting with each other. They do this by forming an enzyme-substrate complex that reduces energy that is required for a specific reaction to occur. Enzymes determine their functions by their shape and structure. Enzymes are made of amino acids, it 's made of anywhere from a hundred to a million amino acids, each they are bonded to other chemical bonds.
Enzymatic Reaction Lab
384 Words | 2 PagesThe purpose of this experiment was to analyze the effects of the variables: temperature, pH, and enzyme concentration, on the enzymatic reaction rate of catalase and the level at which its products are released, measuring the rate of absorption using the indicator solution guaiacol and a spectrophotometer to develop a hypothesis of the ideal conditions for these reactions. My hypothesis is that the extremes in concentration, temperature and pH will negatively affect the Au rate. This experiment used 11 solutions contained in cuvettes. Each cuvette, once mixed, is placed in spectrophotometer and then a reading taken every 20 seconds. Cuvettes 1, 8, and 10 are used as blanks to zero out the spectrophotometer.

1090 Words | 5 PagesIt was hypothesized that the optimal pH for the enzyme was pH 7 while the 1.0 ml peroxidase would have the best reaction rate. At the end of the experiment the results prove the hypothesis to be incorrect. INTRODUCTION Enzymes are proteins that allow a reaction to speed up. These proteins are made up of monomers known as amino acids.

1516 Words | 7 PagesAbstract This experiment showed that temperature, concentration and pH all affect the rate of enzyme reaction differently. Enzymes are very important in organisms and therefore understanding how and why they work the way they do in specific conditions is crucial. The results showed that an increase in temperature would also increase the reaction rate, until a temperature that was too high, where the enzymes began to denature and therefore the rate of reaction was slowed down. As concentration was increased, the reaction rate continued to increase.

2136 Words | 9 PagesThe objective of this lab was to determine the best pH level to increase enzyme activity. As this objective was met, it was discovered that water (pH level 7) was the best for percent absorbance. The hypothesis for this experiment was, “If peroxidase is an enzyme and therefore contains certain pH tolerances, then when placed in solution with pH levels of three, seven, and ten and the reaction is measured by a colorimeter, then water will be the optimal solution for maximum reaction rate.” As seen in the tables and graphs, the data supported the hypothesis due to the fact that most enzymes have an optimal pH of 4-9.

The Biological Temperature Of Catalase
750 Words | 3 PagesIntroduction: Enzymes are biological catalysts that increase the rate of a reaction without being chemically changed. Enzymes are globular proteins that contain an active site. A specific substrate binds to the active site of the enzyme chemically and structurally (4). Enzymes also increase the rate of a reaction by decreasing the activation energy for that reaction which is the minimum energy required for the reaction to take place (3). Multiple factors affect the activity of an enzyme (1).

1182 Words | 5 PagesIntroduction 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.
Bio Chem: Lab Report Of Amylase In Enzyme
916 Words | 4 PagesBio Chem lab Report 04 Enzyme Biochemistry Group Member: Chan Man Jeun Duncan (16002621) Law Sze Man (16000478) Introduction Enzyme is a protein base structure substance in our body. It works at a biocatalyst that will catalyzing the chemical reaction, which helps to speed up the chemical reaction. Enzyme could only function in specific shape, and the shape of enzyme is depending on the environment, therefore it is hard for an enzyme to function well in an extreme environment. The aim of this experiment is to see can the enzyme functions normally in different environment(pH, temperature and salt concentration) via using starch solution, amylase from saliva, 0.5M HCl solution, 0.5M NaOH solution and NaCl solution, and using iodine solution
Effect Of Enzyme Concentration On Enzyme Reaction
1046 Words | 5 PagesAlong with being found in plants, they are also present in liver cells, kidney cells, leukocytes and erythrocytes. For the concentration of enzyme experiment, the hypothesis was if the concentration of an enzyme increases, then the enzyme activity will increase as well. The hypothesis was proven to be true, because there are more enzymes to react with substrates. For the enzyme—factors affecting, the hypothesis concluded was if the temperature increases, than the enzyme activity will increase. This however was proven wrong, because enzymes become unstable at higher temperatures.
