Temperature Of Peroxidase Lab Report
1100 Words | 5 Pages
How Temperature Effects the Catalytic Ability of Peroxidase from Potatoes Abstract In order to determine if temperature affects the ability of Peroxidase to react, we measured the reaction rate of the same solution exposed to different temperatures. Solutions were exposed to a 4-degree, 22-degree, 32-degree, or 60-degree Celsius environment then measured by a spectrophotometer. The solution left in the 22-degree environment had the highest reaction rate, while the solution exposed to the 60-degree water bath was not able to react at all.

The effect of pH on the speed of enzyme interaction with substrate chemicals Hypothesis: About pH: If the pH level is less than 5, then the speed of the enzyme reaction will be slower. About temperature: If the temperature stays the same, then the speed of the enzyme reaction will not be completely affected. Background information: The function of enzymes is to speed up the biochemical reaction by lowering the activation energy, they do this by colliding with the substrate.

It 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.
Enzyme Peroxidase Lab Report

Abstract In this experiment it was examined whether the enzyme peroxidase will work fastest in a pH of 8.0. We placed the enzyme peroxidase in a reaction with guaiacol and hydrogen peroxide in four different pH solutions. Then recorded the absorbencies for each reaction until all substrates were used up, and calculated the initial reaction velocities for each. We found that the reaction in a pH 7.0 solution had the highest initial reaction velocity.

40 celcius. At lower temperatures, sucrase activity begins to be inactive but quickly becomes active. At higher temperatures, sucrase activity Laboratory Report/ Natalie Banc/ Enzyme Activity/ Elizabeth Kraske/ 09.22.2016/ Page [2] of [4] starts to slowly become less active. 4. Was sucrase activity higher at 25 °C or 55 °C?
Peroxidase Lab
224 Words | 1 Pages
The purpose of this study is to investigate the effects of varying the concentration of peroxidase on rate of reaction, as well as, the varying temperature and pH levels. Enzymes are proteins that catalyze biochemical reactions that work by reducing the activation energy for each reaction, causing an increase to the rate of the reaction. One class of enzymes are known as peroxidase. Peroxidase catalyze the oxidation of a particular substrate by hydrogen peroxide. Meaning that it eliminates H2O2 in order to prevent damage to the cells and tissues (Department of Biology University of Tampa 74).
The Biological Temperature Of Catalase
750 Words | 3 Pages
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).
Fair Test Lab Report

The method used was reliable and increased accuracy in the experiment, making it a fair test. This is proven throughout out the experiment because of many reasons such as the controlling the temperature. We did this by making sure the temperature of all enzymes tested, were consistent and had the same temperature, by putting the potato enzymes (Peroxidase) in a boiling tube then in a water bath to at a temperature of 20*c. This ensured a greater accuracy in the results, because if the temperature of some enzymes were higher than the rest, then the rate of reaction for those enzymes would have been faster as particles would move faster as they heat up speeding up the process. Our method was done at 20*c because this is close to room temperature
Catalase Experiment

This is indicated as the graph shows that the initial reaction rate for pH 7 was 0.143 %O2/s compared to 0.047 and 0.053 for pH 6 and 8 respectively. Additionally, Figure 3 indicates that as the pH increases or decreases from 8 and 6 respectively the initial rate of reaction decreases marginally. This is known as the initial rate of reaction for pH 4 and 10 was 0.036 and 0.035 %O2/s, indicating an unsubstantial difference in the initial rate of reaction; for pH 4 and 6 of 0.011 %O2/s and pH 8 and 10 of 0.018 %O2/s. As the pH deviates from 7 the initial rate of reaction decreases as the optimal pH for catalase is 7. As the pH increases or decreases the concentration of hydrogen and hydroxide ions in the solution are altered. These ions alter the shape of the enzyme diminishing the ability for hydrogen peroxide to bind with the active sight of the catalase enzyme in turn decreasing
Effect Of Temperature On Amylase
1167 Words | 5 Pages
Research question What is the effect of temperature Amylase activity? Word count-1453 Background research Enzymes are biological catalysts that speed up a chemical reactions. They do this by decreasing the activation energy(the energy needed to start the reaction) of a chemical reaction. The enzyme present in our saliva is called Amylase. Amylase increases the rate of reaction by decreasing the activation energy needed to hydrolyse the starch molecules.
Effect Of Enzyme Concentration On Enzyme Reaction

ABSTRACT: The purpose of the experiments for week 5 and week 6 support each other in the further understanding of enzyme reactions. During week 5, the effects of a substrate and enzyme concentration on enzyme reaction rate was observed. Week 6, the effects of temperature and inhibitor on a reaction rate were monitored. For testing the effects of concentrations, we needed to use the table that was used in week 3, Cells.
Bacterial Amylase Lab Report
706 Words | 3 Pages
Abstract Enzymes have one active site that empowers the substrate to tie to the enzyme which then structures the enzyme substrate and finally, after, discharges the items. The primary function of enzymes is to control the chemical responses that happen in cells. Fungal and Bacterial amylase are the proteins that were concentrated on for their capacity to separate starch. With a specific end goal to decide how temperature influences the action of amylase enzymes and ideal temperature of fungal and bacterial amylase, the action of these compounds were tried at distinctive temperature and times and iodine was utilized as a marker of starch.

MYP 4: What Is The Effect Of The Concentration Of Catalase
2423 Words | 10 Pages
Isabella Alvares MYP 4 Task due date: 23rd August 2016 Research Question: What is the effect of the concentration of the enzyme Catalase from a potato on the time taken for a paper disc to rise to the top of a hydrogen peroxide substance? A chemical reaction is a process that involves the reorganization of the molecular arrangement of substances. It is the procedure in which a reactants and/or products undergo to form a new substance or molecule; which is the result of an effective chemical reaction. (1) In a reaction, two or more molecules interact, colliding into each other and breaking the bonds between atoms, consequently, creating new molecules and substances.
