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 thorium 7:30pm October 25, 2012 Megan Duell 1 Abstract The utilisation of this taste was to enumeration the e?ects of physical conditions and concentration directs on the military do 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 lively role in many biological processes. They speed up reaction times and greatly reduce needed activating energy. Without enzymes, many chemical substance substance reactions that ar necessary for feel would take many 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 argon more 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. I! t 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 send wordful a?ect the rate at which an enzyme catalyzes a reaction can include temperature, substrate concentration, and pH levels. For example, with too high of caring the enzyme may be...If you want to get a full essay, array of battle it on our website: BestEssayCheap.com
