Conclusions:
An enzyme speeds up the chemical reaction, the activation energy allows energy to require to break bonds apart and lower activation …show more content…
The reactants that enzyme act upon with the substrate and the enzyme will bind together into the active site. The catalyst is important to the enzyme that breaks down the hydrogen peroxide and oxygen gas, where the rate of reaction of the catalyst will increase the temperature until it has reached the optimum temperature above 37°C is reached. If the optimum temperature has reached above 37°C then the kinetic energy and substrate molecules will begin to denature. The purpose of the lab was to determine the effects different temperature in yeast and hydrogen peroxide in a catalyst enzyme on reaction rate. There were many sources of errors that occur in the lab from having just one trial, using the same thermometer for each solution and inaccurate timing. The sources of error of having one trial can result in inaccurate results when having two or three trial can have more of an accurate reaction rate from adding the volume of oxygen gas then divide by two or three to get an average volume of O2. Other sources or errors is reusing the same 250 mL graduated cylinders for each temperature and recleaning causing the solution to be diluted. If we used three 250 mL graduated cylinders for each temperature than the volume of the oxygen gas would go to a faster reaction and the solution
