Enzyme activity The introduction is a statement of the subject and objectives of the experiment and presents your hypothesis. Relevant background information (appropriately referenced) is given in sufficient detail that a person unfamiliar with the topic can understand the nature of the experiment. A good introduction is clear and concise. Carbohydrates and proteins should be explained in terms of their structure and major functions in cells. Your intro should end with a brief overview of the amylase

EcoRI enzyme and deionized water would be put into both tubes. EcoRI enzyme was the restriction enzyme that cut the DNA at the specific sequence. The EcoRI buffer enhanced the stability of many enzymes and binds contaminants that may be present in DNA preparations. DI water was used to bring the solution into a required volume for gel electrophoresis. The prepared sample was incubated at 37℃ for overnight. 40mL of a 0.8% agarose gel is prepared after the preparation of the samples was done. Agarose

Effects of Changes in Physical Properties on Enzyme Activity By Alex Hoffmann First Individual Lab Report Wednesday 7:30-10:15pm 10/24/12 Meghan Duell Abstract The goal of this lab was to determine the effects of certain physical properties on enzyme activity. Enzyme activity was measured by the height of the bubbles that appeared after the enzyme was added which are proportional to the rate of the reaction when time is constant. The fact that enzyme activity is affected by physical

This lesson was about experimenting with Forces and motion. After inquiry 4.1 and 4.2‚ it was best to graph the data to see the differences. Inquiry 1 was used to find out the force needed to move a wooden block over different surfaces. The different surfaces that were used were the Tabletop‚ Waxed paper‚ Paper towel‚ Fine sandpaper‚ and Coarse sandpaper. A spring scale was used to measure the amount of force using the unit Newtons(N). After 3 trials to get one number averaging was necessary. Same

The Effect of Concentration‚ pH and Temperature on Enzyme Activity Biology For Majors October 4‚ 2012 Abstract We examined the reaction an enzyme has when its concentration‚ pH and temperature are altered. In order to do this‚ we added different levels of pH into different test tubes with the enzyme (sucrose)‚ and substrate (sucrose)‚ and we then inverted the tube. The higher pH produced more enzyme activity. Temperature effects enzyme activity by decreasing its stability when the temperature

The Effect Of Substrate Concentration On The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase

Basic Biochemistry CP2085 Effect of Temperature‚ Study and Measure of Enzymes Activity Abstract This experiment investigates the effect that temperature has on the rate of activity of enzyme β-galactosidase and also the rate of β-galactosidase activity in different concentration of substrate over time. Ο-nitrophenylgalactoside (ONPG) is used as a substrate for β-galactosidase. A spectrophotometer is used to detect the change in colour of the substrate. Results show that increase in temperature
