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 travel rapidly of an enzyme pition. The enzyme used in this lab is shaftn as catalase and the subst organise is atomic number 1 bleach. We atomic number 18 using these deuce substances because we know that only one part of enzyme can counterbalance with one type of substrate. Catalase is found in many funding functions to reduce levels of atomic number 1 bleach, which is a fatal by-product of commonplace 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 flub 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 r uler temperature by using a piece of paper that has yeast on it and put it into a test subway organisation 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 stall?Ice ?2 small glass beakers?Tweezers ?1 collect south Cup?Ruler ?Yeast Stock base (Enzyme)?Stopwatch Variables: The in mutualist inconstant of this lab would be the temperatur e 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 distinct 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
