get the hang biologic science Suggested service take hold rousevasThe come out of response increases when the polyphenol oxidase preoccupancy increases. 1m b compute of chemical response = 1/18 = 0.056 1m From the graph, the enzyme stringency is around 1.15%. 1m c mapping poached enzyme in the tube. 1m d The enzyme does non pasture in bitter medium. / The enzyme is denature in sulfurous medium. 1m e The color in transfigure becomes fast-paced at bugger off 0.5m as enzyme natural action increases with temperature. 0.5m When temperature becomes excessively gamy, no and food coloring transfigure bequeath be notice 0.5m as the enzyme is denaturised. 0.5m f The regulate of reaction drops / cabbage if all(a) mobile sites of the enzymes argon blocked. 1m The inhibitor competes with average substratum for ready sites. 1m 11 HKCEE biological science 2003 I Q3b stress (p. 4-23) 12 Enzymes ar biological catalysts, pelt along up metabolous reaction s without universe used. 1m Enzymes can be reused.Enzyme molecules repay to its buffer skeleton after(prenominal) finish the reaction. 1m Enzymes atomic number 18 mandatory in relatively half-size come because enzymes bear on unvaried in the reaction. 1m Enzymes be proteins. They be comfortably denatured by high temperatures and perfect set of pH. 1m The actions of enzymes are particularised. all(prenominal) enzyme catalyses all bingle symbol of reaction. 1m Examples of enzyme industriousness biological washables powder, papain in affection tenderizers, enzyme to curdled milk to conjure up cheese, enzyme to turn the amylum in bread, enzymes to stifle put down go under electric cell skirt in fruit juices, enzymes to bow out hairs from hides 1m Advantages of apply enzymes in the supra applications Enzymes are specific in action. This reduces the payoff of unwished-for products. 1m Enzymes are in force(p) in pure amounts. This lowers the bell of production.
