The effect of time on enzyme reaction. Abstract: In this lab investigation we will observe how the amount of hydrogen peroxide is affected by catalase over time. The enzyme was added to 10 mL’s of hydrogen peroxide and observed over time to determine the relation between time and enzyme activity. The hypothesis stated that as time increased substrate would decrease. Therefore I predicted that at 60 seconds‚ there would be the least amount of H2O2. The enzyme activity mirrored my predictions

BIOLOGY IA A Factor That Will Affect Enzyme Activity The Question Effects on Enzyme activity: investigating the effects of mixing Hydrogen Peroxide with Catalase extracted from potatoes at different temperatures‚ and then comparing the results with the same method‚ except to replace the Potato juice with MnO2 Hypothesis Since enzymes are a type of protein‚ they will be destroyed at high temperatures and activity rates will go down at low temperatures. Also‚ if done at low temperature

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

____________________ Immobilizing an enzyme provides various analytical benefits‚ and can be done in a myriad of ways‚ with the most common being entrapment. For this study peroxidase (from horseradish)‚ an enzyme that catalyzes the cleavage of hydrogen peroxide into water‚ was entrapped within a polyacrylamide gel matrix. The gel matrix was formed by the addition of methylene bis-acrylamide (a cross linking agent) to acrylamide. The immobilized enzyme was then tested via spectrophotometric assay
