The class measured the pressure in the test tube during the reaction of the substance with‚ 1.5 ml of H2O2‚ 1.5ml of H2O and different amounts of enzyme drops‚ to determine how much oxygen gas is produced during the reaction since the pressure of

Conclusion Page 2.)Bibliography Project Abstract: In my project I am trying to figure out if age affects how much you can remember in a short amount of time. My hypothesis was that a middle age person would remember the most. But after I did my experiment I was proven wrong and found out that a teenager remembers the most in a sort amount of time.

because it gives more information faster‚ and that is true except for the fact that students are misusing the power of technology by going off track and essentially missing the lesson being taught. The internet is a great and expansive place‚ and that is why sometimes students rather explore it then listen to their teachers. All these sites and apps are taking up the attention of students throughout the world. This is shown in a Canadian study which proves that computers are helping lower the users grade

Enzymes Lab Report Inroduction In this lab we explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions. It helps accelerate reactions by lowering the activation energy‚ which is needed for reactions in cells to progress at a higher rate. Activation energy is the minimum amount of energy needed for a chemical reaction to occur‚ yielding products from a given set of reactants. (Unit 7: Enzymes lab) Products

____________________ Immobilizing an enzyme provides various analytical benefits‚ and can be done in a myriad of ways‚ with the most common being entrapment. For this study peroxidase (from horseradish)‚ an enzyme that catalyzes the cleavage of hydrogen peroxide into water‚ was entrapped within a polyacrylamide gel matrix. The gel matrix was formed by the addition of methylene bis-acrylamide (a cross linking agent) to acrylamide. The immobilized enzyme was then tested via spectrophotometric assay

Lab 6: Enzymes . header Purpose: The purpose of this lab is to test for enzyme activity‚ look at enzyme specificity‚ and how temperature affects enzyme activity. Time need to perform this lab: approximately 3 hours Preparation FIRST: Read the lab in its entirety TWICE before you begin. You will perform the experiment‚ write your lab report and include the answers to the additional 4 questions within the text for full credit on this experiment. Materials: •3% hydrogen peroxide •a

Factors Affecting Reaction Rate Bob Jones Josh October 2‚ 2014 Period 3 Introduction: In reference to the collision theory‚ molecules act as small spheres that collide and bounce off each other‚ transferring energy among themselves when the collide. In order for a reaction to occur‚ there must be collisions between molecules. Through experimentation‚ factors are discovered that influence the reaction rates of chemical reactions include the concentration

scale Enzyme applications 1. Detergents Bacterial proteinases are still the most important detergent enzymes. Lipases decompose fats into more water-soluble compounds. Amylases are used in detergents to remove starch based stains. 2. Starch hydrolysis and fructose production The use of starch degrading enzymes was the first large scale application of microbial enzymes in food industry. Mainly two enzymes carry out conversion of starch to glucose: alpha-amylase and fungal enzymes. Fructose

Enzyme Reaction to Variable Elizabeth Alvidrez University of Texas at El Paso Abstract: An enzyme is a protein that serves as a biological catalyst (Denniston‚ 2007). Metabolic reactions happen with in cells. Enzymes are proteins that are used to speed up these reactions without being consumed by them (Mader‚ 2010). Catalase is a catalyst that digests potent hydrogen peroxide and converts it into H2O and O (Campbell Reese‚ 2008). The environment plays an important role
