Lab Experiment: Catalase Experiment

1453 Words6 Pages

Catalase Experiment Can hydrogen peroxide be broken down by catalyst other than those found in a living system? Independent and Dependent Variables Independent Variable: The independent variable is the chicken liver and the potato. Dependent Variable: The dependent variable is what I will be measuring which is how much peroxide I will use for each individual experiment. I will also need to measure the temperature of the peroxide during/after the experiment and the pH balance. Purpose “What was the purpose for this lab?”- IRP Instructions The purpose for the Catalase Lab Experiment to have figured out if Hydrogen Peroxide could be broken down by catalyst found in and not in a living system. Background Information Biological catalyst have enzymes which contains …show more content…

Catalase Lab

1410 Words | 6 Pages

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.

Turnip Peroxidase Lab Report

2136 Words | 9 Pages

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.

Bright's Disease Lab Report Sample

Introduction The purpose of this lab was to use chemical and physical tests to identify indicators of disease in synthetic urine samples. This lab tested samples for protein levels, glucose levels, and pH levels. In a normally functioning individual, proteins cannot pass through the glomerulus; therefore proteins should not be found in urine. However, in the nephrons of individuals with Bright’s Disease, the glomerulus no longer stops all proteins from entering the urine (Giuseppe et al., 2002, pp.

Independent Variable amount of substrate (sucrose) present 3. Controlled Variables temperature, pH, sucrase + sucrose incubation time 4. Describe what is measured as an indicator of sucrase activity and why this is an indicator of sucrase activity. I believe glucose and fructose was used as an indicator because they are what produces sucrose and sucrose creates more sucrase activity.

Introduction: 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.

For instance, we could not conclude that mitochondrial activity is present in Supernatant II. However, our experiment showed that the boiled corn kernels did not undergo any mitochondrial activity while the raw corn kernels did. This might indicate that raising the temperature might have an effect on the function of dehydrogenase. Moreover, our found that starch granules are present in both sediment I and the “gunk”. Indeed, some parts of this experiment were not successful because the procedure was not followed

They can only quicken reactions that will eventually occur, but this enables the cell to have a productive metabolism, routing chemicals through metabolic pathways. Enzymes are very specific for the reactions they catalyze; they make sure the chemical processes go in the cell at any given time. Peroxidase was the enzyme being testing in this experiment. A peroxidase is an enzyme that acts as catalysts, which occurs in biological systems. Peroxidase is found in plants, which they play a role in helping to minimize damage caused by stress factors or insect pests.

Bio 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
