here you have to write about your ideas after the experiment was conducted and inform your readers about your thoughts that are based on the results of the experiment. there should be a comparison of your results and your expected findings. write in this section some information about whether your results supported your thesis or there were variances. your interpretation must be original you can write from being specific to general , do not prove disprove your hypothesis. add some original ideas to your interpretation and end with a concluding statement. ✏ ️ example: proteins catalyze reactions by bringing down the activation energy of the reaction; catecholase an enzyme discovered in potato changes catechol to benzoquinone with the presence of oxygen. we expected that more benzoquinone would be shaped by the presence of a more noteworthy measure of catecholase. this theory was proven by the outcomes acquired. listed below are some cell biology research topics: 1. molecular cell biology of diabetic complications 2.

you also just observed the effects of catalase on the reaction in which hydrogen peroxide breaks down into water and oxygen. enzymes speed the rate of chemical reactions. a catalyst is a chemical involved in but not consumed in a chemical reaction. enzymes are proteins that catalyze biochemical reactions by lowering the activation energy necessary to break the chemical bonds in reactants and form new chemical bonds in the products. catalysts bring reactants closer together in the appropriate orientation weaken bonds increasing the reaction rate. without enzymes, chemical reactions would occur too slowly to sustain life. the functionality of an enzyme is determined by the shape of the enzyme. the area bio 101 lab report in which bonds of the reactant( s) are broken is known as the active site. the reactants of enzyme catalyzed reactions are called substrates. the active site of an enzyme recognizes , confines orients the substrate in a particular direction. dissertation uzh rwi.
