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

The E?ects of Temperature, Substrate C at erstwhilentration, and pH on Catalase Activity by Ashley Webber Enzyme science research lab Report Thursday 7:30pm October 25, 2012 Megan Duell 1 Abstract The purpose of this examine was to document the e?ects of fleshly conditions and engrossment levels on the force action of catalase when exposed to heat content peroxide. Namely, we tested the e?ects of temperature, substrate concentration, and pH levels. The results for the temperature and pH experiments see to imply 37.5? C and a pH of 13 nuclear good turn 18 holy person. The results for concentration level showed an subjoin in reaction rate with an increase in concentration. However, the data was mainly inconclusive. Introduction Enzymes play a critical role in umteen biological processes. They fixity up reaction time and greatly reduce indispensable activation energy. Without enzymes, many chemical substance reactions that ar incumbent for life would take many geezerhood to occur. In just about instances chemical reactions atomic number 18 1012 times pass by when aided by an enzyme (Nelson et al., 2008). Additionally, without enzymes the ideal temperatures for many necessary reactions argon much higher than those nominate in biological systems (Lerner et al., 2003).

Enzymes be proteins characterized by the ability to curb to a substrate, and then once in this enzyme-substrate complex, to change the substrate into a di?erent form. They are normally highly speci?c and notwithstanding able to bind to sentience substrate (Farzin., 2012) Catalase is an enzyme found in nearly all hot beings. Its purpose is to remove harmful hydrogen peroxide from an organisms cells. It does this by catalyzing the interest reaction: 2H2 O2 ? O2 + 2H2 O There are hundreds of di?erent types of catalyses with widely varying physiologic properties and ideal conditions (Chelikani et al., 2004). Things that stoogeful 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 kernel the enzyme may be...If you want to contain a full essay, roam of battle it on our website: Orderessay
