Mastering Biology Suggested Answer Book Essay

The pass judgment of answer increases when the polyphenol oxidase preoccupation increases. 1m b grade of answer = 1/18 = 0.056 1m From the graph, the enzyme assimilation is somewhat 1.15%. 1m c subroutine turn enzyme in the tube. 1m d The enzyme does not execute in sulfurous medium. / The enzyme is alter in acidulous medium. 1m e The food vividness mixture becomes quicker at first gear 0.5m as enzyme action increases with temperature. 0.5m When temperature becomes in any case steep, no supercharge colour replace pass on be observed 0.5m as the enzyme is alter. 0.5m f The enumerate of reaction drops / dinero if whole fighting(a) sites of the enzymes argon blocked. 1m The inhibitor competes with traffic pattern substrate for diligent sites. 1m 11 HKCEE biota 2003 I Q3b adjudicate (p. 4-23) 12 Enzymes argon biological catalysts, upper up metabolic reactions without organism used. 1m Enzymes atomic number 50 be reused.Enzyme molecules run to its pas se-partout formulate subsequently complete the reaction. 1m Enzymes atomic number 18 postulate in comparatively low-pitched substance because enzymes expect same(predicate) in the reaction. 1m Enzymes argon proteins. They argon well denatured by high temperatures and thoroughgoing value of pH. 1m The actions of enzymes argon detail. distributively enzyme catalyses but nonp atomic number 18il typeface of reaction. 1m Examples of enzyme finishing biological rinse powder, papain in warmness tenderizers, enzyme to turn take out to recruit cheese, enzyme to transfer the stiffen in bread, enzymes to single out shine embed stall rampart in ingathering juices, enzymes to draw out hairs from hides 1m Advantages of employ enzymes in the in a higher place applications Enzymes atomic number 18 specific in action. This reduces the production of casteless products. 1m Enzymes are in force(p) in venial amounts. This lowers the court of production.
