Catalase, is an enzyme where hydrogen peroxide is broken down to water and oxygen ; which causes a response. Found in a lot organisms that live in the surrounding of oxygen, catalase can fend off the buildup and protects cellular organs from damage by peroxide, which is always produced by many reactions. The catalase enzyme is critically important to are health, it can be found in nearly every living organism exposed to oxygen. In the catalase lab we measured the amount of catalase in each ingredient by combining each ingredient with hydrogen peroxide and sticking into a test tube emerged under water to measure the amount of oxygen.
The object of the lab was to test the four substances and test them to see which one has the highest amount of catalase. The dependent variable was the amount of oxygen and the independent variable was the four substances; potato, carrots, yeast, and lettuce because they stood on their own. For our group data lettuce had the most catalase with an oxygen level of 20 ml and potato had the least with 6 ml of oxygen. Our class data shows that yeast has the most catalase with an oxygen level at 20.5ml…
they become denatured. Denaturation of an enzyme can occur with changes in factors such as temperature, pH, or salinity.
The enzyme being used in this experiment is catalase. Catalase is an antioxidant enzyme that helps to…
Enzymes are biological catalysts that help speed chemical reactions. In part A (table 2), it was seen that a normal reaction of catalase and hydrogen peroxide resulted in the release of bubbles (oxygen gas) and the release of energy in the form of heat which shows that the reaction was a exothermic reaction. The reaction was given a reaction rate of four and acted as the control with which we could compare the other results to. When testing whether or not catalase is reusable in part…
Catalase is an iron porphyrin enzyme present in high concentrations in humans and animals liver tissues. It is a peroxisomal enzyme that is responsible for destruction of toxic H2O2 released during certain metabolic processes.The activity of catalase can be determined by measuring the decrease in H2O2 concentration which is the substrate.
An enzyme is a large protein that acts as a biological catalyst which changes the rate of a reaction. It provides an active site…
catalysis breaks down hydrogen peroxide into water and oxygen. In this lab we conducted a series of experiment to find the effect of concentration of substrate and the temperature of catalase enzyme.
Introduction: There are a lot of factors that can affect the rate of enzyme reaction such as the concentration of the substrate, temperature of the enzyme, and shape of the enzyme. In this experiment we only measure how the concentration of the substrate and temperature of the enzyme affects the…
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.
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,…
Temperature and Substrate Concentration on Catalase
Biology 101 Lab Section 041
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…
The effect different temperatures have on the rate an enzyme works was tested by 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…
Temperature on a Catalase Reaction Rate
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 the experiment completed,…

February 23, 2017
This investigation is geared towards observing the enzyme reaction times in Solanum tuberosum, also known as the common potato, depending on the temperature of the catalase. During the lab, students tested the reaction times of the catalase when placed in hydrogen peroxide when the…
