Hypothesis: I hypothesis that the enzyme concentration will affect the rate of reaction but only up until a certain point because there is a limited supply of substrate. Enzymes are protein molecule that acts as biological catalyst by increasing the rate of reactions without changing the overall process. They are long chain amino acids bound together by peptide bonds. Enzymes are seen in all living cells and controlling the metabolic processes in which they converted nutrients into energy and new

ID:0720052 Effect of an Increasing Substrate Concentration on Enzyme Activity Rate Abstract The reaction rate of an enzyme can be affected by many factors‚ and the purpose of this experiment was to find out how an increasing substrate concentration influences the rate of an enzyme activity; we obtained data from recording the absorbance of the samples which contain the same amount of potato juice (enzyme oxidase) and different amount of catechol (substrate) while holding pH and temperature constant

Substrate concentration and yeast catalase Aim: To see how the substrate concentration in hydrogen peroxide affects the rate of an enzyme controlled reaction using yeast catalase. Introduction: An enzyme is a biological catalyst made of protein. Enzymes are protein molecules found in living organisms and in this case I will use a yeast catalase. Catalase is an enzyme that catalyzes the reduction of hydrogen peroxide. Hydrogen peroxide is a poisonous by-product of metabolism‚ so it is very

experiment to investigate how the concentration of an acid affects the rate of the reaction. I have set up the experiment’s equipment as shown on figure 1. As you can see by figure 1‚ I have used the reaction between sodium thisoulphate solution and hydrochloric acid (HCL) to come up with results that will help me draw conclusions regarding the effects of the concentration of the acid. I decided to use this particular reaction due to the fact that the product of the reaction between sodium thisoulphate

investigating how the rate of reaction differs when we change the concentration of Hydrochloric Acid whilst reacting with Magnesium. The rate of reaction is explained by the Collision Theory. This theory explains how various factors affect the reaction rates and how chemical reactions occur. The 4 factors of the Collision Theory are: • Temperature • Concentration • Surface area • Catalyst I am investigating how different concentrations of acids affect the rate of reaction. However I must control

different Substrate Concentrations (3%‚ 1% and 0.3%) as 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

Summary This experiment will measure the rate of oxidation of iodide ions by persulphate ions to derive the rate law for the reaction. Starch will be added to the reaction to facilitate the measure of time during the reaction. The reactant solutions will contain (NH4)2SO4 and KI‚ represented as: (NH4)2S2O8 + 2KI -> I2 + (NH4)2SO4 + K2SO4 This can be simplified to: S2O82- + 2I- -> I2 + 2SO42- These equations can only be carried out and be visible after the iodine has completely

How Different Concentration Effects The Rate Of Reaction. Strategy A Possible Factors * Source of catalase * Concentration * Surface Area of enzyme * Concentration of enzyme * pH * Temperature Chosen Factor We chose to investigate the concentration of enzyme as we had previously investigated the optimum temperature for catalase in the preliminary investigation. Concentration of enzyme is also fairly easy to investigate‚ as you need to only increase the amount of

An Investigation on the rate of reaction of the enzyme Catalase on the substrate Hydrogen peroxide. Plan Aim: To investigate the rate of the effect of Catalase on hydrogen peroxide. Introduction This investigation will be carried out to investigate the rate of reaction of the enzyme catalase on the substrate hydrogen peroxide. Enzymes are biological catalysts‚ which speed up the rate of reaction without being used up during the reaction‚ which take place in living organisms. They do this by
