The effect of various temperatures on Enzyme activity
Introduction: The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life's processes would not happen easily. An enzyme is a macromolecule serving as a catalyst, they are generally a protein based molecule, as it is in the lab, Enzymes are organic catalysts that control the rate of chemical reactions in cells while not being permanently changed or without being consumed, which makes enzymes different from other proteins. In general, enzymes speed up the rate of reactions by lowering the activation energy required to start reactions. Furthermore, Enzymes are extremely well organized. They can catalyze reactions at rates up to 10 billion times higher than non-catalyzed reactions. Due to their particular shape, they hold the reactant molecules in closeness and in the correct position for the reaction to …show more content…
Tube A, which was left in a cold temperature, had less fizzing (8.5cm); tube C produced medium amount of fizzing (10.5cm) and tube B had a greater fizzing which was 11cm. The result data that we collected after the experiment supported our hypothesis.
Catalase concentration: Upon adding the potato pieces to the test tubes while waiting to measure the production of O2, we noticed right away that tube A is not doing anything because its only contains hydrogen peroxide and not any enzyme catalase to start the reaction while tube B, which contained 1cm potato piece produced 7.7cm fizzing, tube C, which contained 2cm potato piece produced 8.5cm fizzing and tube C, that contained 4cm potato piece had a greater amount of O2 (11.5cm) in form of
