The Effects of Temperature, Substrate Concentration, and Ph on Catalase Activity

The E?ects of Temperature, Substrate C at oncentration, and pH on Catalase Activity by Ashley Webber Enzyme science laboratory Report atomic number 90 7:30pm October 25, 2012 Megan Duell 1 Abstract The social function of this taste was to inventory the e?ects of physical conditions and concentration take aims on the military deed of catalase when exposed to hydrogen peroxide. Namely, we tested the e?ects of temperature, substratum concentration, and pH levels. The results for the temperature and pH experiments seem to imply 37.5? C and a pH of 13 atomic number 18 ideal. The results for concentration level showed an increase in reaction rate with an increase in concentration. However, the data was chiefly inconclusive. Introduction Enzymes play a precise role in many biological processes. They speed up reaction times and greatly reduce needed activating energy. Without enzymes, many chemic substance reactions that ar necessary for life history would take man y geezerhood to occur. In some instances chemical reactions atomic number 18 1012 times fleet when assisted by an enzyme (Nelson et al., 2008). Additionally, without enzymes the ideal temperatures for many necessary reactions are some(prenominal) higher than those found in biological systems (Lerner et al., 2003). Enzymes are proteins characterized by the ability to bind to a substrate, and then once in this enzyme-substrate complex, to change the substrate into a di?erent form. They are usually extremely speci?c and only able to bind to star substrate (Farzin., 2012) Catalase is an enzyme found in nearly all alive organisms. Its purpose is to remove toxic hydrogen peroxide from an organisms cells. It does this by catalyzing the following reaction: 2H2 O2 ? O2 + 2H2 O There are hundreds of di?erent types of catalyses with widely varying physical properties and ideal conditions (Chelikani et al., 2004). Things that faecesful a?ect the rate at which an enzyme catalyze s a reaction can include temperature, substr! ate concentration, and pH levels. For example, with too high of inwardness the enzyme may be...If you want to get a full essay, society of battle it on our website: BestEssayCheap.com
