The Effect of Subst lay Concentration on Enzyme Activity Doug Alexander, tease 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 public presentation of catalase in yeast by use hydrogen bleach as its substrate. In from each one trial, we utilize polar amounts of hydrogen peroxide while using a constant quantity 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): bring 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 science lab surgical operation except for steps 4 and 6 which we did non do. (Enzyme Catalysis Lab., 2007-2008) normal Lab Procedure: 1. Work as a lab throng of 3-4 members. Each lab throng ordain accomplish Part A and Part B of the lab. Your teacher provide assign on an additional activity to each group form Parts C, D, E & F. 2.

At your lab workbench you will find a cycle per second phial with a rubber stopper top. This is called the reaction chamber. You will too 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 experimental apparatus, as described and illustrated below. 3. Fill the pan 3/4 full of tap water. Allow the water to do it to mode temperat! ure. 4. Submerge the 100mL graduated cylinder to fill it with water. moment the graduated cylinder top down, keeping the open annihilate chthonic water, so as to keep it filled with water. exclude it upside down in the clamp on the ring rise. set up the height of the clamp on the ring stand so the open end of the graduated cylinder is about 3cm in a higher place the...If you want to get a full essay, direct it on our website: OrderEssay.net
