Abstract The aim of this study was to test the rate of reactivity of the enzyme catalase on hydrogen peroxide while subject to different concentrations of an inhibitor. The hypothesis was that hydrogen peroxide will be broken down by catalase into hydrogen and oxygen‚ where a higher concentration of inhibitor will yield less oxygen‚ resultant of a lower rate of reaction. Crushed potato samples of equal weight were placed in hydrogen peroxide solutions of various temperatures. The results showed

An investigation to see how much oxygen is given off when different concentrations of catalase are added with hydrogen peroxide. Aim: To see if changing the concentration of catalase (found in celery) with hydrogen peroxide affects the amount of oxygen given of. Background Information: (Hydrogen peroxide - H2O2 1/2O2+H2O) Enzymes: Hundreds of chemical reactions happen simultaneously inside living cells and it’s the job of enzymes to control and regulate the various metabolic

Testing Catalase Activity Prepared by Anel Behric For professor Goodrow General Biology Lab Mohawk Valley Community College 10/14/2014 6:00 PM Introduction: This experiment was conducted to examine the breakdown of substrate hydrogen peroxide (H2O2) by catalase‚ which is a specific enzyme that breaks down substrates of (H2O2). Molecules are in our bodies and nature. They move around constantly which causes them to be part of random collisions‚

Experimental Research Craig S. Ricard PSY/285 Due: March 11‚ 2012 Experimental Research Recently‚ a group of teachers wanted to determine the effectiveness of using anti-bacterial gels against the spreading of germs from person to person and overall preventing them from getting the cold or flu. In order to see if using anti-bacterial gels prevents getting the flu or a cold an experiment must be performed with the teachers. The experiment must be properly performed by randomly dividing

Myers Beaird MUSC109: Intro to Experimental Music Final Exam/Response Question Fall 2013 In the words of John Cage‚ “I compose music. Yes‚ but how? I gave up making choices. In their place I put the asking of questions.” Just having performed John Cage’s Musicircus‚ I found it only fitting to relate my own piece to the excerpt above. What questions did I have prior to developing the piece? I was curious about the sounds that could be created if I were to amplify the situation of shaving my

Both groups will have equivalent numbers of males and females and they will all have the basic knowledge of swimming. Group one‚ the experimental group will have ten (10) males and ten(10) females and group two‚ the control group will also have the same number of males and females. They are picked at random from ages 15 to 35. A regular swimming pool is used. On the day of experimenting

Assignment 2 - Experimental Design Project Rekha Arora Department of Computer Science Rochester Institute of Technology ABSTRACT It is estimated that 43% of United States population is functionally illiterate [1]. On the other hand‚ the health system in United States is budding and people are being more health conscious and aware. The big question is how we can integrate the healthcare awareness in the illiterate people such that they can also take advantage of the evolving healthcare
