How Enzymes Work In Different Environments By Sarah Smith Biology1111 October 20‚ 2011 Lab Partner: Nellie Greer ABSTRACT Peroxidase is an enzyme found in potatoes that catalyzes the breakdown of hydrogen peroxide‚ H2O2‚ into O2 gas and water. We examined the different pH environments that can affect the enzyme activity during the breakdown of H2O2. In order to do this‚ we added different levels of pH‚ low‚ medium‚ and high‚ into different test tubes with the enzyme and H2O2‚

Project Enzymes are organic catalysts produced by living organisms which aid in the progression of specific biochemical reactions without undergoing any permanent chemical changes themselves. They are complex‚ conjugated proteins necessary and required to sustain life. Today‚ enzymes are also used world-wide in a variety of different industrial applications such as the production of paper‚ wine fermentation‚ and bio-remediation. One of the most important industrial applications enzymes are used

The Rate of Reaction that Enzyme Concentration‚ pH‚ and Temperatures Have on the Amylase Enzymes Color Disappearance Abstract: Compare reaction rates of the concentrations‚ pH’s‚ and temperatures of the enzyme Amylase. At what concentrates do the substrate molecules collide with each other‚ making the reaction possible? At what pH levels do the 3D molecular structures change breaking the H-bond and/or denaturize? At what temperatures do the collisions of the substrate molecules happen

I. Preparation A. Choosing 1. You should choose the fruits that you like. a. For example‚ if you desire to gain more different fruits enzymes or make the glass bottle more colorful‚ you can choose four or even more kind of fruits. There is no limitation. But‚ you must include one fruit‚ lemon. It helps to kill the bacteria of the drink. B. Composing 1. The ratio of components should be 3‚ 1. It means 3 parts of fruits‚ 1 part of sugar. You can follow this ratio to determine the amount of fruit

There are many reasons why enzymes have such a high specificity. The first variable is an enzyme’s primary structure. A primary structure is just a combination of amino acids. There are twenty different amino acids that the primary structure can be created from. Every enzyme has a different order that the acids are placed in and each one has a different number or amino acids. The slightest change in this structure can affect a protein’s conformation and function. The secondary structure is a regular

Action of enzymes as catalysts in biochemical processes * Enzymes acts as catalyst and increase the rate of all the chemical reactions. * Enzymes are also described by two properties like all other catalysts. It composed of two main functions. * The first function is that‚ they increase the rate of chemical reactions by without consumed themselves or undergo any change or alteration in the reaction. . ( Zemitec et‚al 2008). * The second function is‚ they increase reaction rates
