Catalase

contain more catalase than the other. The reaction rate between the chicken liver and the hydrogen peroxide was quite fast as opposed to the potato and hydrogen peroxide which was at a slow to a moderate rate. This is most likely due to the fact that cellular respiration occurs more often in animals than plants, meaning that they would have a higher ammount of catalase. 2. Test tube 5 had a greater reaction rate than test tube 4. In test tube 4, there was a higher concentration of catalase…

discover how different number of pH levels react towards the enzyme catalase, found in beef liver, and will be discovered by the number of oxygen bubbles through the degradation of hydrogen peroxide. Hypothesis The higher the pH level, the more production of oxygen bubbles in the solution. Variables Could affect activity of catalase - Temperature of reactant vessel - Concentration of Hydrogen Peroxide/Catalase - pH level of Hydrogen Peroxide - Competitive/Non…

What is a catalase? A catalase is an enzyme that destroys harmful substances inside your body, and is a form of protein. (Corsini, "What Is a Catalase?") What is an enzyme? Enzymes are substances that speed up chemical reactions. (Corsini, "What Is a Catalase?”) This experiment involved both of these two aspects. It was inferred before the experiment began that if the potato is placed in hydrogen peroxide at room temperature, then it will produce the most bubbling activity. The reason that the…

substances are combined. The oxygen gas, as a product, comes from the hydrogen peroxide. Enzymes are big proteins that speed up the rate of a chemical reaction by moving as a catalyst. A catalyst provides the environment for the reaction to occur. Catalase is an enzyme in the liver that breaks down dangerous hydrogen peroxide into water and oxygen. When this reaction takes place, oxygen gas bubbles breakout and create foam/bubbles. For our procedure, we used 4 different experiments, one in each…

The crude extract containing a catalase, catalyse a reaction where the substance is simultaneously oxidized and reduced, giving two different products of H2O to O2 and H2O. This reaction was measured by UV-Vis spectroscopy which results a decrease in absorbance at 240nm. The decrease in absorbance was caused by the loss of H202 in a product. The catalase enzyme was purified by the 5 – step procedure using a sodium phosphate buffer and a DEAE- Sepharose column which is mainly used for protein…

Catalase Enzyme Lab Write-Up Our goal with this lab is to discover how enzymes affect the production and destruction of harmful chemicals our body makes into harmless chemicals. Our body contains hundreds of enzymes in our cells and this lab will show us how they interact with parts and materials of our bodies. The enzyme we will be focusing on is called catalase. It’s job for the body is to break down hydrogen peroxide a harmful substance into two harmless substances oxygen and water.…

on Catalase Kristen Clark Biology 101 Lab Section 041 9/22/14 Brandon Stroup Abstract Catalase is an enzyme found in every living organism and is essential for cells. This lab explores how catalase reacts to four different temperatures and how the concentration percentage of substrate affects its reaction rate. The performance of catalase is dependent on many factors, so the purpose of the lab was to find the ideal concentration and temperature for catalase. We hypothesized that catalase…

this lab. The concentration of the enzyme catalase in different types of cell was also tested. Enzymes are balls of protein that change a specific substrate into a product by contact at the active site. Enzymes are reusable and once they finish tuning one substrate into a product, it moves on to the next substrate it bumps into in just the right way. The enzyme catalase, which this lab focuses on, can be found in the tissues of plants and animals. Catalase is very important because it takes in…

Aim: This is an investigation to establish the effect of different temperatures (from 0°C -100°C) on the production of oxygen gas in a potato catalase reaction, using hydrogen peroxide as a substrate. The oxygen gas produced will be measured using a gas pressure sensor. Introduction: Enzymes are proteins, known as biological catalysts that increase the rate of reaction in a biochemical reaction without being chemically altered. The human body consists of various different types of enzymes,…

Substrate Concentration and Temperature on a Catalase Reaction Rate Introduction Catalase is a vital component in the human body. The most crucial of which would be Enzymes, these are protein catalysts. A catalyst speeds up a chemical reaction rate. Virtually all chemical reactions within the human body require a catalase enzyme to be completed in the proper amount of time. The decomposition of hydrogen peroxide to oxygen and water can be completed with the catalase enzyme (Thompson, 2005). In…
