The effect of subst sum up concentration on the tramp of reply of the enzyme catalyses. Aim To measure the rate of reception by looking at the amount of oxygen given onward when a barm culture b is added to different concentrations of henry peroxide Background information An enzyme is a biologic catalyst. They fixture up the rate of a reaction until now they atomic number 18 not affected themselves whilst doing this, this is why they argon catalysts. Enzymes atomic number 18 do to be specific, this means that they can have hardly unity substrate that they leave alone work on. Each enzyme has an progressive site that is where their own specific substrate molecule go away fit. Enzymes all work best at an optimum temperature that is ordinarily body temperature at 37C. If the temperature that the enzyme has to work at gets too high, usually 40C it will start to become denatured and therefore no longer work on its substrate as the lively site has changed shape. In addition, enzymes usually work best at an optimum pH level, this is normally seven because enzymes are proteins which are damaged by actually acidic or real alkaline conditions. Most reactions work better at higher(prenominal) temperatures, this is because molecules fall upon rough much quicker. This makes the molecules have more get to bump around with the substrate.
With more collisions, there is more lot of a reaction-taking place. This makes the rate of reaction faster. At 40C the enzyme starts to be damaged, this slows the reaction and by around 60C the enzyme will be completely destroyed. When these bond s are broken, the enzyme, along with the ex! peditious site, is deformed, thus deactivating the enzyme. This is know as a denatured enzyme The maneuver and advert theory Emil Fischer originated the lock and key theory in 1894. It states that...
