Environmental Variables and their effect on Horseradish Peroxidase Abstract There are several factors that can affect the rate of reaction of peroxidase such as temperature‚ pH‚ concentration of peroxidase present and whether or not it has been boiled. Our experimental data demonstrated that peroxidase activity peaked between 23 degrees Celsius and 32 degrees Celsius. We found the pH to be 7 for optimal activity. As far as the concentration is concerned our results showed that as the concentration

The experimental results were different from the hypothesis because while the enzyme appeared to not work as well‚ I expected a more significant change. Most of the time‚ there was only a millimeter of difference of the foam between the two samples while I expected a greater difference such as 10 millimeters. Enzymes speed up chemical reactions and at the active site‚ a substrate can be broken down or two substrates can form a larger molecule. Hydrogen peroxide is broken down by peroxidase into water

Add 1.26g of oxalic acid dihydrate (H2C2O4.2H2O) and 1 ml of concentrated ammonia. Stir the mixture until the solid has dissolved completely. Dissolve 2.34 g of cobalt chloride hexahydrate (CoCl2.6H2O) in 100 ml of water

I have come up with an experiment to test the 3 variables to figure out what treatments if any will work the best. My hypothesis is that all 3 of the suggestive treatments when done before flying on an airplane‚ will reduce the effects of jet lag. Experiment: A commercial airplane traveling from New York City to Los Angles non –stop will be selected at random. All passengers will be randomly

In my experiment of breaking the norm‚ I did two different things. in one of my “experiments” I would hold doors anywhere I where for the people that were behind me and wait for a response‚ when the person was educated enough to say thank you I would smile and let it go. When the opposite happened‚ whenever the person behind me did not say thank you I would compliment myself. I would thank myself for holding the door instead. The first time I conducted this specific experiment I was at

EXPERIMENTATION - 1953 Urey and Miller collaborate effectively to design an experiment/model to simulate conditions on early Earth and test the hypothesis that life molecules could originate on Earth 4.

Conclusion The purpose of our experiment was to determine if reading off words in various colors helped improve memory. Our hypothesis was that color helped memory and it was in fact proven by our experiments. According to data table 2‚ the average words remembered by the white control group was 6.4‚ while the other groups with the colors had averages of 6.8 and 8.2. Our hypothesis also proven in table 3‚ where the average words remembered by the control was 4.6 and the other two groups had averages

INTRODUCTION The Loftus and Palmer experiment investigated the influence of leading information: visual imagery and leading questions with regards to eyewitness testimony. A research that studies this is the Loftus and Palmer (1974) Experiment. It aims is to investigate how “verb” asked in the question causes construction in one’s memory of that event. Participants will be separated into two groups one control and one test group‚ then both groups will view a video of a car crash. After that‚ the

In the Milgram experiment‚ a man picks random people to participate in an experiment. They believe that they are helping discover the roles of punishment on behavior. Although‚ this is not true. The participants themselves are the ones being analyzed. The experiment is to discover how far someone would obey an instruction of harming another person‚ despite personal conflict. The participant and an actor are places in a room and “get to choose” their roles of either teacher or learner‚ although the

In the human stomach‚ particularly those of infants‚ rennin works to curdle milk so that pepsin‚ another stomach enzyme‚ can further breakdown the proteins into absorbable amino acids called polypeptides. The aim of this experiment is to investigate the effect of changing temperature on the activity of enzymes. After experimentation the optimum temperature for enzyme activity will be established and the effects
