Biology Lab report 1 The progeny of divers(prenominal) submerging of catalase on total heat hydrogen peroxide Aim: To see the effect of different concentration of catalase on hydrogen peroxide as heedful by the amount of oxygen provided range information Enzymes argon outlined as a course of proteins which catalyze chemical reactions. As enzymes work by move activation energy, the reactions would happen at a very riotous rate. Thus, the reactants of the reactions ar called substrates. In addition, active agent site is a special region where the substrates bind on the surface of the enzyme. Because of the enzyme-substrate specificity, they exactly founder a very teentsy number of come-at-able substrates which also means that they could catalyze in very a couple of(prenominal) reactions. In short, not all the substrates could have the reaction with enzyme. Catalase, the enzyme we are using in this experiment, could react with hydrogen peroxide, the subst rate of the experiment. heat content peroxide (H2O2) is an oxidizer which is a expel liquid commonly used as a bleach. It is brutal and can damage cells if it is not removed properly. Catalase, a biologic (organic) catalyst is an enzyme that speeds up the break vote out of hydrogen peroxide into piss (H2O) and oxygen triggerman (O2).

There are some factors that would presume the reaction of enzyme, which is, temperature, pH and substrate and enzyme concentration. Enzyme bodily function increases as temperature increases and they are denatured at spirited temperatures. The optimum of the pH is where e nzyme employment is the fastest. Enzyme oc! cupation increases or decreases as pH increases or decreases. Enzyme activity increases steeply when substrate concentration increases at low substrate concentration. However, as most of the active sites are occupied at high substrate concentration, there would only be belittled effect on the enzyme activity when the substrate concentration increases. In this experiment, we are going to work with the concentration of enzyme. independent...If you want to break down a full essay, order it on our website: BestEssayCheap.com
