Biology Lab report 1 The matter of divers(prenominal) concentration of catalase on total heat hydrogen peroxide Aim: To hold the effect of different concentration of catalase on hydrogen peroxide as heedful by the amount of oxygen provided accentuate information Enzymes atomic number 18 outlined as a resistant of proteins which catalyze chemical reactions. As enzymes work by hard activation energy, the reactions would happen at a very tight rate. Thus, the reactants of the reactions are 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 scarce founder a very teentsy number of realistic substrates which also means that they could catalyze in very fewer 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 subs trate of the experiment. henry peroxide (H2O2) is an oxidizer which is a expel liquid normally used as a bleach. It is brutal and can injury cells if it is not removed properly. Catalase, a biologic (organic) catalyst is an enzyme that speeds up the break grim of hydrogen peroxide into piss (H2O) and oxygen shove off (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 laid-back temperatures. The optimum of the pH is where enzyme employment is the fastest. E nzyme bodily process 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
