The effect of subst sum up concentration on the count of reply of the enzyme catalyses. Aim To measure the rate of chemical reaction by looking at the amount of oxygen given remove when a barm culture b is added to different concentrations of heat content peroxide Background information An enzyme is a biologic catalyst. They drive up the rate of a reaction until now they argon not affected themselves whilst doing this, this is why they atomic number 18 catalysts. Enzymes are do to be specific, this means that they can have hardly superstar substrate that they leave alone work on. Each enzyme has an liberalist site that is where their own specific substrate molecule pass on fit. Enzymes all work best at an optimum temperature that is unremarkably body temperature at 37C. If the temperature that the enzyme has to work at gets too high, ordinarily 40C it will start to become denatured and therefore no longer work on its substrate as the spry 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 truly alkaline conditions. Most reactions work better at high temperatures, this is because molecules fall upon rough much quicker. This makes the molecules have more lay on the line to bump around with the substrate.
With more collisions, there is more destiny 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 t hese bonds are broken, the enzyme, along wit! h the expeditious site, is deformed, thus deactivating the enzyme. This is know as a denatured enzyme The maneuver and delineate theory Emil Fischer originated the lock and key theory in 1894. It states that...
