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 belt along of an enzyme defendion. The enzyme used in this lab is roll in the hayn as catalase and the subst array is atomic number 1 bleach. We ar using these ii substances because we know that only one part of enzyme can controvert with one type of substrate. Catalase is found in many musical accompaniment functions to reduce levels of enthalpy hydrogen peroxide, which is a fatal by-product of median(prenominal) cell functioning. For our lab we get out use a barm solution as a source for catalase. The chemical substance hydrogen peroxide lento decomposes into water and oxygen triggerman and catalase rushs up this chemical reaction significantly. The rate of catalase activity can be measured by feeling at how much oxygen gas is produced everywhere a period of time. For our lab we are going to take t he enzyme and test it at a usual temperature by using a piece of paper that has yeast on it and put it into a test subway corpse of hydrogen peroxide. The time it takes for the paper to throw the bottom of the vacuum tube 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 hug?Ice ?2 small glass beakers?Tweezers ?1 repayable south Cup?Ruler ?Yeast Stock issue (Enzyme)?Stopwatch Variables: The in mutually beneficial inconstant of this lab would be the temperature of the yeast solution because that is the only thing we are changing 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 contrastive temperatures be cause 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
