Introduction Enzymes are proteins produced by living organisms to speed up the rate in which chemical reactions occur. This process can happen fast‚ slowly‚ or stop the chemical reaction all together depending on the temperature‚ pH and concentration. Catalase is one of the most common enzymes. It is found in living organisms and is used to break down hydrogen peroxide. This must happen because hydrogen peroxide is considered toxic to cells in the body. However‚ when catalase is used it breaks

Temperature and enzyme activity Aim: To determine the effect of which the temperature of the enzyme has on the rate of the enzyme catalysed reaction. Hypothesis: The rate of reaction of an enzyme catalysed reaction will increase as the temperature of the enzyme approaches the optimum temperature. Surpassing the optimum temperature will result in a drop in enzyme activity. Materials: 6% hydrogen peroxide Liver suspension 10 test tubes 4 beakers Thermometers Measuring cylinders Test

acidity of a solution influences the reaction rates‚ such as those involved in food spoilage. Objective Students will be able to describe the effects of the temperature of a solution on reaction rates and support their thinking using data from the investigation. Guiding Question How does the temperature of a solution affect a reaction rate? Pre-planning This lesson will have students investigating the effect of temperature on a simple chemical reaction‚ effervescent tablets bubbling in

Chemical reactions are at the heart of all biological processes. The body must regulate precisely all the chemical reactions going on in order to maintain life. Much of this regulation is done by changing the activity of enzymes.(www.biology.kenyon.edu) Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells.(www.livescience.com) Enzymes speed up chemical reactions by providing an alternate

at how the concentration of acid can change the reaction and how I can explain this using collision theory. My Prediction: I predict that the greater amount of concentration the faster the reaction will take place. Therefore‚ particles in the two compounds will collide faster. Due to my prediction if it is correct‚ I expect to see the cross on the paper disappear faster. As I already know that increasing one quantity will speed up the reaction as the particles are more likely to collide.

Title- Effecting the Reaction Rate in Enzymes in Plants and Animals Problem- How do variables temperature and surface area affect the rate of reaction occurring in the enzyme? Information- Enzymes are proteins that act as biological catalysts. They speed up chemical reactions that take place in cells. Enzymes can be found in both liver and potato. They provide a site where reactants can be brought together to react. These reactants are called substrates that fin into the enzyme. The changing

which one was the fastest to react‚ I hypothesized that the reaction would occur the fastest with the 3% hydrogen peroxide (the highest amount of concentration) because the higher the concentration the more faster the reaction occurs and helps produce or break up the enzyme. After testing all three of my substrate concentrations with 10 trials each‚ my data showed (first graph) that the 3% substrate concentration had the fastest average rate at 0.19 of distance and time occurring and my second data

Introduction: Enzymes are a substance produced by a living organism that acts as a catalyst to activate a specific reaction. The purpose of this experiment was to figure out if the temperature of the reaction would rise‚ will the absorption rise as well. Reactions use energy‚ If there is energy than heat occurs. The Hypothesis that was figured out was‚ If the temperature rises‚ then the absorption will also go up. The Independent variable that was tested was temperature. The dependent variable that

The Relationship between Reactants and Products Introduction In a chemical reaction‚ the amount of starting material for a chemical reaction limits the amount of product that can be formed.1 The principle of limiting reactants relates to this lab because the limiting reactant is the substance that is used up first in a chemical reaction. The amount of product was limited by that reagent. The excess reactants were considered to be the other reagents that were presented in excess of the quantity that

thermometer and record the start temperature of each trial. Then we will place the tube to the flame with different height differences with each trial (2 in‚ 3 in‚ and 4 in). When each reaction is placed we will then record the highest temperature the water heated too. Then we will measure the the cheeto and record the after reaction mass. Then using the nutritional value 160 cal per 28 grams we will use the equation (accepted - experimental divided by accepted multiplied by 100) to get the percent error.
