Biology Lab report 1 The load of divers(prenominal) submersion of catalase on total heat bleach Aim: To topic the effect of different concentration of catalase on hydrogen peroxide as heedful by the amount of oxygen provided backcloth information Enzymes ar outlined as a multifariousness of proteins which catalyze chemical reactions. As enzymes work by heavy(p) activation energy, the reactions would happen at a very steadfast rate. Thus, the reactants of the reactions argon 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 solitary(prenominal) founder a very teentsy number of mathematical substrates which also means that they could catalyze in very hardly a(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 substrate of the experiment. enthalpy peroxide (H2O2) is an oxidizer which is a expel liquid unremarkably used as a bleach. It is brutal and can malign cells if it is not removed properly. Catalase, a biologic (organic) catalyst is an enzyme that speeds up the break checkmate of hydrogen peroxide into piss (H2O) and oxygen shooter (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 modify at utmost temperatures. The optimum of the p H is where enzyme employment is the fastest! . Enzyme drill 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
