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 effect of catalase in yeast by use hydrogen hydrogen bleach as its substrate. In from each one trial, we utilize opposite amounts of hydrogen peroxide while using a never-ending 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): make the following materials: 50mL beaker containing fresh catalase (Boghog2, 2008) (yeast) solution reaction chamber 10mL gradual cylinder 100mL have cylinder 3% hydrogen peroxide (H2O2) pan (water bath) pipette thermometer distilled water We followed this general laboratory map except for steps 4 and 6 which we did non do. (Enzyme Catalysi s Lab., 2007-2008) frequent Lab Procedure: 1. Work as a lab throng of 3-4 members. Each lab sort out ordain fill in Part A and Part B of the lab. Your teacher get out assign on an additional activity to each group form Parts C, D, E & F. 2.

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