Enzyme Catalysis Lab: Laboratory Write Up Problem/Question: What happens to the amounts of gas produced in a catalyzed reaction of Hydrogen Peroxide when the catalyst is mixed with an acid? Theory/Hypothesis: In this experiment the researcher and their team will be performing tests on a catalyst (proteins found in potato) to see what will happen when the catalyst in a Hydrogen Peroxide reaction is treated with an acid before the reaction occurs. The researcher hypothesizes that the after treating

The purpose of this investigation is to find out the relationship between the substrate concentration and the rate of reaction. Substrates are molecules that are acted upon by enzymes. For instance‚ amylase‚ an enzyme found in saliva‚ helps break

What are Enzymes? Enzymes are proteins that quicken chemical reaction in our body. They are found in our digestive system‚ in the stomach mostly. They are there to speed up the process of breaking down food into molecules that provide nutrients to the body. Enzymes are made up of amino acids. The Digestive System: Many people believe that when you eat a meal it drops into a pool of stomach acid‚ and then it is broken down as it goes into the small intestine to have nutrients taken out‚ and then

The Effect of Concentration‚ pH and Temperature on Enzyme Activity Biology For Majors October 4‚ 2012 Abstract We examined the reaction an enzyme has when its concentration‚ pH and temperature are altered. In order to do this‚ we added different levels of pH into different test tubes with the enzyme (sucrose)‚ and substrate (sucrose)‚ and we then inverted the tube. The higher pH produced more enzyme activity. Temperature effects enzyme activity by decreasing its stability when the temperature

Abstract: Enzymes help determine a phenotype through proteins. The experiment presented tests how enzymes affect the pigment in the eye of Drosophila. What was resulted in this experiment is that when certain enzymes change‚ a mutation is created‚ causing the change of pigments in the different Drosophila’s eyes. The production of one enzyme is one gene and a mutation of this gene can cause an enzyme to be inactive which leads to the phenotype changing. Introduction: George W. Beadle and Edward L

Part I - Introduction Enzymes are proteins that act as catalysts to regulate metabolism by selectively speeding up chemical reactions in the cell without being consumed during the process. During the catalytic action‚ the enzyme binds to the substrate – the reactant enzyme acts on – and forms an enzyme-substrate complex to convert the substrate into the product. Each type of enzyme combines with its specific substrate‚ which is recognized by the shape. In the enzymatic reaction‚ the initial rate

Enzyme Lab Write-Up Purpose: To observe how an enzyme affect the speed of chemical reaction. To describe how the concentration of an enzyme affects its ability to work. Hypothesis: Depending on the concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of catalysis such as an enzyme. Moreover to

Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially

College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded
