The activity of an Enzyme is affected by its environmental conditions and changing these factors can alter the overall rate of the reaction. Reaction rates are influenced by external factors such as pH‚ temperature and salt concentration. Different enzymes have different optimum temperatures in which they are most efficient and different pH levels which is ideal for their formation of enzyme-substrate complexes. As the temperature increases‚ there is more movement of molecules and more random collisions

Enzyme Lab 6 03/13/2013 Report by Mary Jo Anthony I. Introduction II. Materials and Methods III. Results IV. Conclusion and Discussion Introduction Background Information: This lab allowed us to study chemical reactions and how catalysts will affect the rate of these reactions. The reaction we studied is the breakdown of hydrogen peroxide to water and oxygen and it is vital to life. The molecule hydrogen peroxide is a molecule that is toxic

Factors that affect how the PH changes during a titration experiment. Concentration of the alkali Having a higher concentration of alkali will mean that there will be more molecules closer together for the acid to collide with. This will speed up the reaction as collision theory suggests that molecules have to collide to react and if there are more molecules to collide with the reaction will happen faster as there is a higher chance of a collision. Volume of alkali An increase in volume would mean

Lab Report: Scientific Method Your Name: Taylah Harness Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? The goal for this lab is to be able to get the boiling water’s temperature to increase by adding table salt. The problem it is trying to explain is‚ how does table salt affect the boiling temperature of water? does it increase or decrease? or does it stay the same? Hypothesis After reading the lab

Task: Investigation of a Factor Affecting Enzyme ActionAspects Assessed: D DCP CE MS Introduction:Thousands of enzymes are found in living cells. In addition to making life possible‚ many enzymes have numerous applications that affect our daily lives in other ways such as food processing‚ clinical diagnoses‚ sewage treatment‚ and the textile industry. In this activity you will investigate how a particular factor influences the action of an enzyme. Conditions: Students are NOT required

Enzymes An enzyme is a protein used to speed up the rate of a chemical reaction. Because they regulate the rate of chemical reactions‚ they are also called catalysts. There are many‚ many different types of enzymes‚ because for each chemical reaction that occurs‚ an enzyme specific to that reaction must be made. To act on a substrate‚ an enzyme must contain an active site. The active site is the area on the enzyme that allows the substrate and enzyme to fit together. The amino acids that are present

Enzymes are catalysts that speed up chemical reaction but are not themselves consumed or changed by the reaction. The cell’s biological catalysts are proteins. Proteins are made up of one or more polypeptide chains that are folded to make an active site‚ an area in which a material to be acted on by the enzyme‚ called the substrate‚ will fit. The temperature‚pH‚ the concentration of enzyme‚ and the concentration of substrate all affect the activity of the enzyme and the rate of the reaction. The

Enzyme activity The introduction is a statement of the subject and objectives of the experiment and presents your hypothesis. Relevant background information (appropriately referenced) is given in sufficient detail that a person unfamiliar with the topic can understand the nature of the experiment. A good introduction is clear and concise. Carbohydrates and proteins should be explained in terms of their structure and major functions in cells. Your intro should end with a brief overview of the amylase

Lab Report: Purpose: The Objective of this lab was to learn how to measure the pH (or acidity) of commonly known fluids‚ using the correct tools and procedures. To then use that data to document the changes noticed when mixing those same fluids and changing their respective pH levels. Materials: In order to conduct this experiment several pieces of equipment and other materials were needed. The first item was a graduated cylinder‚ which was used in order to measure out the precise
