Lab Assignment #9 – EnzymesIntroductionEvery chemical reaction in the cell requires a catalyst.Enzymesspeed up chemical reactions bylowering the activation energy for that reaction.Activation energyis a barrier that must belowered before a reaction can take place. This may involve bringing two molecules together,breaking a chemical bond, or another event that makes it easier for the reaction to occur. Becausethe enzyme is not truly a part of the chemical reaction, it is not consumed during the reaction andtherefore may be used many times.Pre-Lab Questions:1.How does an enzyme affect a chemical reaction?enzymes speed up chemical reactions bylowering the activation energy for that reaction.2.Are enzymes reusable?Why or why not?yes, the enzyme is not truly a part of the chemicalreaction, it is not consumed during the reaction and therefore may be used many times.3.
