The Effect of Subst lay Concentration on Enzyme Activity Doug Alexander, twit Cohen, Erik Nilsson, Mirei Ogawa, moth miller Wren November 6, 2008 November 13, 2008 [pic] Abstract By Mirei Ogawa In our experiment, we examined enzyme subroutine of catalase in yeast by use hydrogen bleach as its substrate. In from each one trial, we utilize unlike amounts of hydrogen peroxide while using a ceaseless amount of catalase and determined whether the reaction rate increased or decreased as the amount of substrates increased. Materials (Enzyme contact action Lab., 2007-2008): win the following materials: 50mL beaker containing fresh catalase (Boghog2, 2008) (yeast) solution reaction chamber 10mL calibrated cylinder 100mL graduated cylinder 3% hydrogen peroxide (H2O2) pan (water bath) pipette thermometer distilled water We followed this general research lab mapping except for steps 4 and 6 which we did non do. (Enzyme Catal ysis Lab., 2007-2008) ordinary Lab Procedure: 1. Work as a lab throng of 3-4 members. Each lab radical ordain commit Part A and Part B of the lab. Your teacher bequeath assign on an additional activity to each group form Parts C, D, E & F. 2.

At your lab patio you will find a cycle per second ampul with a rubber stopper top. This is called the reaction chamber. You will withal find a 100mL graduated cylinder, anticipate tin and clamp, and a plastic pan which will be used as a water bath. All of this equipment needs to be assembled into our data-based apparatus, as described and illustrated below. 3. Fill the pan 3/4 fu ll of tap water. Allow the water to do it t! o manner temperature. 4. Submerge the 100mL graduated cylinder to fill it with water. moment the graduated cylinder crown down, keeping the open annihilate on a lower floor water, so as to keep it filled with water. exclude it upside down in the clamp on the ring rise. specify the height of the clamp on the ring stand so the open end of the graduated cylinder is about 3cm supra the...If you want to get a full essay, direct it on our website: BestEssayCheap.com
