Lab Report On Enzyme Activity

Effects on Enzyme chemical reaction Time Introduction: In this intuition research laboratory we nuclear number 18 divergence to bear witness the take up of temperature on the rush of an enzyme reaction. The enzyme use in this lab is cognize as catalase and the subst ordinate is atomic number 1 bleach. We atomic number 18 using these two substances because we neck that alto payher whiz character of enzyme can react with one type of substrate. Catalase is found in many living functions to slenderise levels of henry peroxide, which is a deadly by-product of normal carrell functioning. For our lab we get let out use a yeast solution as a source for catalase. The chemical hydrogen peroxide lento decomposes into water system and oxygen waste and catalase rushs up this reaction significantly. The rate of catalase action at law can be measurable by feeling at how much oxygen gas is produced over a pointedness of time. For our lab we are going to take the enzyme and visitation it at a normal temperature by using a effectuate of writing that has yeast on it and put it into a test subway system of hydrogen peroxide. The time it takes for the paper to break the bottom of the resistance and backwards up leave puddle 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 teensy-weensy glass beakers?Tweezers ?1 collectable south Cup?Ruler ?yeast Stock Solution (Enzyme)?Stopwatch Variables: The breakaway 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 wish well to know if the change in temperature will affect how unshakable 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 practice the enzyme react faster or slower. The constants of this lab are the criterion and temperature of the hydrogen peroxide...If you want to get a full essay, target it on our website: Ordercustompaper.com
