Title : THE EFFECT OF PH ON THE ACTIVITY OF CATALASE Aim : To study the effect of pH on the activity of catalase. Introduction : Catalase‚ an enzyme found in many different tissues‚ catalyses the breakdown of hydrogen peroxide into water and oxygen. 2 H202 → 2H20 + O2 Hydrogen peroxide is a toxic substance that can be formed during aerobic respiration and catalase removes this product. The activity of catalase can be measured by finding the rate of oxygen release from hydrogen peroxide

CHAPTER ONE GENERAL INTRODUCTION 1.0 Background of the study Poverty is a widespread canker worldwide and every government has stepped in to save her citizens by adopting various policies. Poverty‚ to many authors‚ is the prime symptom of all diseases and early death of many people; especially in the developing countries where income is generally low‚ savings are hardly talked of resulting in low investment and employment. In the Sub-Saharan region‚ Ghana is no exclusion of the poverty story

As the queen of Spain‚ there have been many difficult occurrences I’ve had to deal with during the past few years. I believe that colonization in the New World led to most of them. Spain and America would have been better off if we never started our own civilization there and barged in on the natives. Although there were many complex and tragic events‚ people may argue that some good came out of civilization. There may be some valid points‚ but none of it was worth the damage it caused.

Date: 03/20/2013 Lab: # Purpose of this lab: To test for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme is the optimal environment that an enzyme requires to function
