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 upsurge of an enzyme replyion. The enzyme used in this lab is chousen as catalase and the subst vow is atomic number 1 bleach. We ar using these cardinal substances because we know that only one part of enzyme can pit with one type of substrate. Catalase is found in many subsisting functions to reduce levels of enthalpy peroxide, which is a fatal by-product of frequent 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 burn out 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 oer a period of time. For our lab we are going to take the enzyme and test it at a shape temperature by using a piece of paper that has yeast on it and put it into a test subway remains of hydrogen peroxide. The time it takes for the paper to throw the bottom of the resistance 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 rag?Ice ?2 small glass beakers?Tweezers ?1 receivable south Cup?Ruler ?Yeast Stock resolve (Enzyme)?Stopwatch Variables: The in qualified inconstant of this lab would be the temperature of the yeast solution because th at is the only thing we are changing over an! d 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 polar 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
