How the concentration of enzymes controls the breakdown of heat content Peroxide?Aim- We are investigating the cause of changing the concentration of the enzyme catalase has on the rate of jailbreak down of Hydrogen Peroxide.Background Info- This experiment allow involve some soft potato. potato has a very high enzyme count, thats why we use it in this experiment. This enzyme is called catalase. It is used in our body to break down food and early(a) things that we might digest. A catalase speeds up the rate of receptions. The enzymes are all variable molecules. We will also use Hydrogen Peroxide and washing up liquid. The catalase breaks down the Hydrogen Peroxide into oxygen and water. The more vigorous the reaction the more froth that it creates.The reaction in the experimentHydrogen bleach oxygen + water2H2O2 O2 + H2O The enzyme give the sack be used near the body to help chemical reactions, it speeds them up The enzyme breaks up larger molecules into little pieces. This is how the enzymes work below I have described some of the things that can affect how well it works.Fair bear witness/ Factors-Temp- This can affect the accomplishment of the particles. The higher the temporaryorary the faster the particles will move and the more collisions. If the temp of the Hydrogen Peroxide is too low the experiment will dropHigh Temp- It gives them more energy so they move faster this meaning that they are likely to connect the substrate and the quick site. The high temp also gives the particles kinetic energy. This means that the Hydrogen Peroxide will be broken down quicker.Best Temp- This is the hottest the enzyme can be heated without the expeditious site changing (denaturing). If the active site changes then the reaction will no longer work. From our preliminary test we found out that the optimal temp is 25oc this is around room temp.PH- All enzymes have an optimum PH, the incorrect PH can cause denaturing. The Ph cant be too acid or alkalin e so keep it as near to 7 as possible. If the enzyme denatures then it is no use for breaking down the Hydrogen Peroxide.Concentration of H2O2- The higher the concentration the more collisions with the active site. This means there is an increased rate of reaction. Creating more froth so the concentration will have to be the same for each of the test tubes.
