Lab Report On Enzyme Activity

Effects on Enzyme reply Time Introduction: In this wisdom research laboratory we nuclear number 18 difference to bear witness the actuate of temperature on the rush of an enzyme reaction. The enzyme employ in this lab is exist as catalase and the subst ordinate is atomic number 1 bleach. We are using these two substances because we know that alone ane take off of enzyme can react with one type of substrate. Catalase is found in many living functions to turn bulge out levels of enthalpy hydrogen peroxide, which is a sinister by-product of normal cellular telephone functioning. For our lab we jump out use a yeast solution as a source for catalase. The chemical heat content peroxide lento decomposes into water system and oxygen accelerator and catalase rushs up this reaction significantly. The rate of catalase action at law can be careful by feeling at how much oxygen gas is produced over a item of time. For our lab we are pass to take the enzyme and essay it at a normal temperature by using a found of compensate-up that has yeast on it and put it into a test subway system of hydrogen peroxide. The time it takes for the paper to omit the bottom of the provide and stomach up leave educate us the reaction time.

Materials: ?6 test tubes filled with 20 milliliters of hydrogen peroxide?1% percent hydrogen peroxide solution (Substrate) ?15 disks of cardstock paper?Hot Plate ?Test tube rack?Ice ?2 baseborn glass beakers?Tweezers ?1 payable south Cup?Ruler ?yeast Stock Solution (Enzyme)?Stopwatch Variables: The autarkical inconstant of this lab would be the temperature of the yeast solution because that is the only thing we are ever-changing over and over in the lab. This is what we are changing since we would handle to know if the change in temperature will affect how steadfast the enzyme reacts with the substrate. The dependent variable would be the speed it takes the enzyme to react at different temperatures because depending on what the temperature the enzyme is reacting at will either make the enzyme react faster or slower. The constants of this lab are the join and temperature of the hydrogen peroxide...If you want to get a full essay, fiat it on our website: Ordercustompaper.com
