Introduction In this experiment I aim to find out if caffeine has an effect on the heart rate of daphnia. Daphnia are water fleas that have a sort of heart that we can see in magnification. We can count the number of heart beats in a minute of a regular daphnia and try and get a new one with the same specifications as the old one that may have died. It is also a good idea to get a new one as we want to see how much it affects it from ordinary instead of adding the caffeine one after another

Parachute experiment Aim: The aim was to find the effect of holes on a parachute‚ varying their size and number. Hypothesis: 1. By increasing the number of holes‚ the time it will take to the parachute to reach the ground will be longer and its flight will be more balanced. 2. By increasing the size of the hole on the parachute‚ the time it will take to the parachute to reach the ground will be shorter and its flight will be less balanced. Apparatus: - garbage bag (squared shape

Bradford Method Paul Alcala‚ Andrea Basa‚ Melissa Caagbay‚ Frances Cayomba Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines Abstract The Bradford method used to determine the protein content of a certain solution (Menguito‚ 2010) and involves the acidic Coomassie Brilliant Blue G-250 as a coloring reagent. [1] The dye is originally pinkish-brown in color when it is in its acidic state. When protein is bound to the dye the color turns blue. In this experiment a standard

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

………………………………………………………………………………..9 Properties of Enzymes and Competitive Inhibitors. Abstract: Properties of enzymes were found in this experiment and some other factors‚ which affect enzyme activity. Enzymes are catalyst; they catalyze very specific reactions. Results relating to the active site of specific enzymes played a big role while performing this experiment. The purpose of this experiment was to fin how inhibitors affect enzyme’s activity by competing for the active

Design of a Psychological Experiment Psyc 100 (0110-0129) Fall‚ 1996 Dr. Sternheim Report #1 (10 points) Problem: Suppose you are a psychologist who is interested in the effects of caffeine on the eye-hand coordination of students enrolled at UMCP. Design an experiment to test the hypothesis that caffeine enhances a student’s ability to hit a baseball. Describe your experiment by answering the following questions: 1) What are the independent and dependent variables? The independent variable

Abstract The main goal of the enzyme kinetics experiment was to see how the phosphatase-catalyzed hydrolysis of p-nitrophenyl produced p-nitrophenol in the presence of phosphate and fluoride ion inhibitors of various concentrations. The calculated Km constant was found to be 0.22 for all reactions. The Vmax values for each inhibition ion were 0.00986 for the phosphate ion and 0.00436 for the fluoride ion. The inhibitor constant‚ Ki‚ was determined to be 0.0967 for the phosphate ion. The inhibitor

Rate of Enzyme Activity: Through the Experiment of Beef Liver Puree and Hydrogen Peroxide Research Question Does different amount of substrate affect the rate of enzyme activities? Purpose To examine how different types of concentration (Hydrogen Peroxide) affect the rate of enzyme activity. Hypothesis We believe that if there is more substrate concentrated‚ then there will be an increase in the rate of enzyme activity. This is because we assume the more substrate an enzyme gets
