Enzyme on hydrochloric acid and yeast.

The effect of subst sum up concentration on the calculate of reply of the enzyme catalyses. Aim To measure the rate of reaction by looking at the amount of oxygen given collide with when a barm culture b is added to different concentrations of hydrogen peroxide Background information An enzyme is a biologic catalyst. They secureness up the rate of a reaction until now they argon not affected themselves whilst doing this, this is why they are catalysts. Enzymes are make to be specific, this means that they can have hardly 1 substrate that they leave alone work on. Each enzyme has an reform-minded site that is where their own specific substrate molecule bequeath 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, unremarkably 40C it will start to become denatured and therefore no longer work on its substrate as the agile site has changed shape. In additio n, enzymes usually work best at an optimum pH level, this is normally seven because enzymes are proteins which are damaged by actually acidic or in truth alkaline conditions. Most reactions work better at high temperatures, this is because molecules fall upon rough much quicker. This makes the molecules have more accident to bump around with the substrate.

With more collisions, there is more feel 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 bonds are broke n, the enzyme, along with the expeditious s! ite, is deformed, thus deactivating the enzyme. This is know as a denatured enzyme The maneuver and notice theory Emil Fischer originated the lock and key theory in 1894. It states that...
