Test Tube Degrees Celsius
1,267 wordsEnzyme Action: Testing Catalase Activity Enzymes are proteins that serve as catalysts and accelerate chemical reactions in living organisms. Enzymes accomplish this by lowering the energy of activation of the organism it is acting upon, however enzymes will only lower the energy of activation for specific organisms, reducing chaotic chemical reactions. The reaction is carried out in its entirety in the active site of the enzyme. The substrate (organism acted upon), binds itself into the active s...

H 2 O Rate Of Reaction
1,374 wordsTitle: The Effects of Substrate Concentration and Temperature on the Rate of Hydrolysis of the Enzyme Trypsin. Abstract: Quantitative measurements can relate both temperature and substrate concentration to the enzymatic activity of trypsin. By analyzing the data, it is suggested that at BAPNA concentrations below those corresponding to Vmax are rate limiting, as less active sights are available for adhesion. The values of Vmax and Km relate a temperate catalytic efficiency of trypsin. The temper...

Three And Four Reaction Rate
859 wordsTitle: Examining Some Properties of the Enzyme -amylase In this experiment a deeper meaning in the catalysts of reactions is studied. Catalysts accelerate chemical reactions without permanently changing the reaction. Enzymes, catalysts in biochemical reactions, are globular proteins which lower the activation energy needed to begin a reaction and therefore increase the rate at which efficient reactions can occur. Proteins (henceforth enzymes) are complex molecules made of amino acids in polypept...

Rate Of Reaction Hydrogen Bonding
2,165 wordsRESEARCH I know that Rennin is an enzyme, so before conducting this experiment I am first going to do some research into enzymes and their effects. 1. Enzymes Enzymes are large globular molecules of which the vast majority are protein in nature, though some, known as 'ribozyme's' are made of RNA. Enzymes have catalytic properties; in other words, they alter the rate of reaction without themselves undergoing a permanent change. Most chemical reactions require an initial input of energy, called ac...

Plan for pH I am going to use the three categories of acid, neutral and alkaline to test how pH affects the rate of the enzyme rennin. Whilst studying the affects of varying the pH, I am going to ensure that all other variables are constant. Therefore, I will continue to use 2 ml of milk and 4 drops of rennin. The temperature I shall conduct these expe...

Rate Of Reaction Reaction Rate
1,069 wordsThe purpose of this experiment is to measure the rates of reaction of the enzyme Alkaline Phosphatase with the substrate p-nitro phenol phosphate under varying conditions. The concentration of both substrate and enzyme were diluted and the inhibitor vanadate was utilized to determine whether or not the reaction is substrate or enzyme dependent and to see what type of inhibition vanadate was involved. A class of proteins called enzymes catalyzes almost every chemical reaction in a cell. Enzymes i...

Gel Electrophoresis Carbon Dioxide
2,361 wordsPyruvate Decarboxylase There are two functions of the pyruvate decarboxylase. Pyruvate and hydroxythyl converge together while carbon dioxide molecules are eliminated. Than, hydroxy ethyl group transfers and attaches to TPP to the lipo amide from the E 2 component of the complex. The final transfer brings the molecule back to its original form. (Function) The molecular weight of the enzyme was found to be 240, 000 by polyacrylamide gel electrophoresis (Oba). There are 548 amino acids and very si...

Rate Of Reaction Bunsen Burner
2,301 wordsFor this investigation I am going to investigate the effect of the concentration of an enzyme, in this case Amylase, on the time taken for the enzyme to fully breakdown the substrate, which in this case is starch. The reason why these two enzymes have to be used is because each enzyme is designed specifically to break down only one substrate as each enzyme is made of a protein that causes it to be a specific shape, in this case the enzyme Amylase can only break down starch to dextrin. I am going...

Degrees Celsius Test Tubes
1,993 wordsEffects of Temperature, pH, and Gelatin on Bromelain Introduction Bromelain is an organic catalyst that speeds up the rate of chemical reactions. Bromelain is used in this experiment to catalyze the break down of proteins and is called a proteolytic enzyme. Enzymes enable reactions to occur at a lower temperature and energy levels. This allows many reactions to occur inside living organisms that would otherwise have been impossible to take place. This enzyme is found in fruits, leaves, and stems...

Fifteen Minutes Reaction Time
686 wordsAbstract: The Enzyme Report Enzyme Activity Abstract: The purpose of this experiment is to test the effects of different sugar types with pH and temperatures. We are testing to see if there is a difference in reaction and reaction time when placed into different temperature and pH. We are looking for changes in color, solidity, reaction time, etc. My hypothesis is that at different temperatures and amounts of pH, there will we different reactions. Introduction: The overview of these experiments ...

Lab Manual E Coli
1,139 wordsGene Regulation Using the Lac Operon Abstract Gene regulation in cells has been studied extensively in both eukaryotic and prokaryotic organisms. Gene control is employed as a way of saving the cell energy by only producing those enzymes it needs. In eukaryotes, genes are regulated so as maintain levels of cell specificity. In this experiment, the restriction of the production of the -galactosidase enzyme in the prokaryote Escherichia coli can be achieved by employing the lac operon. This operon...
