investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature)‚ 0 degrees Celsius (freezing)‚ 100 degrees Celsius (boiling)‚ and 37 degrees Celsius. Along with variations in temperature‚ the experiment

TITLE: Enzymes AIM: To investigate the effect of temperature on the enzyme lipase INTRODUCTION: The phenomenon of catalysis makes possible biochemical reactions necessary for all life processes. Catalysis is defined as the acceleration of a chemical reaction by some substance which itself undergoes no permanent chemical change. The catalysts of biochemical reactions are enzymes and are responsible for bringing about almost all of the chemical reactions in living organisms. Without enzymes‚ these

The Effect Of Enzyme Concentration On Enzyme Activity The pancreatic duct in individuals who have cystic fibrosis frequently becomes blocked‚ reducing or preventing the release of pancreatic enzymes into the small intestine. The aim of this activity is to investigate the effect of a reduction in enzyme concentration on the rate of reaction‚ in this case the breakdown of protein by protease enzymes. Aim – Milk powder contains a white protein called casein. A white suspension of

on Peroxidase Enzyme Claire Bell Biology 1130 Jazmen Myers Section 36 Abstract Peroxidase is a turnip enzyme; it is used in the oxidation of hydrogen peroxide to lower activation energy‚ speeding up the reaction. The activity of peroxidase is highly dependent on its environment and most importantly the pH level. Peroxidase has been the focus of many recent studies and is believed to possibly reduce swelling among other things. We conducted an experiment testing the effect different

NaCl Effects on Peroxidase Activity My experiment was to see if adding NaCl to solution would have any effects on peroxidase activity. The materials that were used in this experiment were pH 7 buffer(DI water)‚ peroxidase‚ NaCl‚ guaiacol and hydrogen peroxide; added in that order. Blanks were created for each NaCl concentration‚ 0%‚ 5%‚ 7.5% and 10%. Each cuvette had .5ml of pH 7 buffer‚ 1ml of peroxidase‚ .02ml guaiacol for the experimental cuvettes and 0ml of guaiacol for the blank cuvettes‚

What effect does temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one

Enzymes are important components of life‚ facilitating reactions that are necessary for an organism to live. Enzymes can be very specific to what environment they function best in1. Numerous environmental impacts were tested for the enzyme peroxidase which catalyzes the decomposition of hydrogen peroxide. The basic decomposition reaction was carried out first without any environmental alterations. The hypothesis for this reaction was supported. The enzyme caused the amount of absorbance increase

In this lab the peroxidase enzyme is tested in a dormant avocado seed as well as an avocado seed undergoing the process of germination. A gas pressure will be used to test the seeds and see if the peroxidase enzyme is present in either of the seeds. A catalyst is very similar to track spikes. Spikes increase a runner’s speed‚ as a catalyst speeds up the chemical reaction time in a plant. Neither the catalyst nor shoes are changed in these actions. Enzymes are macromolecules that act like catalysts

test for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme is the optimal environment that an enzyme requires to function‚ which means having the optimum ph and temperature to catalyze a
