Lab Report On Enzyme Activity

Effects on Enzyme Reaction Time Introduction: In this science research laboratory we atomic number 18 going to bear witness the affect of temperature on the knock of an enzyme respondion. The enzyme used in this lab is getn as catalase and the subst put is atomic number 1 bleach. We argon using these both substances because we know that only one part of enzyme can reply with one type of substrate. Catalase is found in many live functions to reduce levels of hydrogen hydrogen peroxide, which is a fatal by-product of convening cell functioning. For our lab we get out use a barm solution as a source for catalase. The chemical hydrogen peroxide lento decomposes into water and atomic number 8 mishandle and catalase rushs up this reaction significantly. The rate of catalase activity can be measured by feeling at how much oxygen gas is produced over a period of time. For our lab we are going to take the enzyme and test it at a regular temperature by using a p iece of paper that has barm on it and put it into a test subway organization of hydrogen peroxide. The time it takes for the paper to throw the bottom of the thermionic valve and back up leave ready 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 torture?Ice ?2 small glass beakers?Tweezers ?1 ascribable south Cup?Ruler ?Yeast Stock consequence (Enzyme)?Stopwatch Variables: The in subject inconstant of this lab would be the temperature of the yeast solut ion because that is the only thing we are ch! anging over and over in the lab. This is what we are changing since we would like to know if the change in temperature will affect how fast the enzyme reacts with the substrate. The dependent variable would be the speed it takes the enzyme to react at diametric 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 amount and temperature of the hydrogen peroxide...If you want to get a full essay, order it on our website: OrderCustomPaper.com
