Omar Shbeeb Toothpick Enzyme Lab 9/25/13 Introduction Enzymes are used in all metabolic reactions to control the rate of reactions and decrease the amount of energy necessary for the reaction to take place. They are responsible for the thousands of chemical interconversions that sustain life. Enzymes are referred to highly selective catalysts‚ meaning they speed up the rate of metabolic reactions. To react‚ they need to find a perfect match with a substrate. They converge at a place called an

Purpose: Restriction enzymes cut DNA at a certain palindromic sequence. Three samples of lamda DNA set up to be cut with restriction enzymes PstI‚ EcoRI‚ or HindDIII. There were also two more samples‚ one of these samples was not mixed with any restriction enzyme and the other was a marker‚ which used an enzyme which creates fragments with a known number of base pairs used to create a standard curve. All five samples were put through agarose gel electrophoresis in order to estimate the amount of

Biology Digestive Enzyme Experiment “Design an experiment in which you will investigate a digestive enzyme’s effect on digestion” Research Question: To determine the effect of enzyme concentration on the rate of digestion. This will be done by increasing the concentration of the enzyme diastase and investigate its effect on the rate of starch digestion. The rate will be determined by the amount of time it takes to completely digest the powdered starch‚ the complete digestion will be indicated by

for the effects of temperature on the enzyme activity was that the reaction’s rate would increase as the temperature increased‚ until they go over the optimum temperature where the enzymes denature and the reaction’s rate quickly drops to zero. At 5 degree C the rate is 0.00059mole PNP/min. This then increases to 0.01031mmoles PNP/min at a temperature of 50 degree C. The rate then drops drastically to -0.00215moles PNP/min. This point is where the enzymes have been denatured and have no activity

Property Ownership in Quebec Partnerships: Who Really Owns the Property? As opposed to U.S. partnership law‚ which holds property brought into or acquired by the partnership becomes property of the partnership; in Quebec‚ you can bring the property into a partnership and have it considered separate from other partnership property (Kubasek‚ M.‚ Herron‚ Dhooge‚ & Barkacs‚ 2013). Under the Civil Code of Quebec (CCQ)‚ in the area of contributing property to the partnership; made by the transfer of

temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the difference absorbance levels they produced every 20 seconds for about 2 minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What we got from the experiment was at lower temperature we got very low numbers for the absorbance‚ which gave us a lower rate for the enzyme reaction to complete‚
