Lab 2 Enzyme Catalysis Day 1 learn Concepts : Enzymes catalyse chemical receptions by spurning the activation dynamism needed for a chemical reaction to occur. The molecule that an enzyme acts on is called the subst compute. In an enzyme-mediated reaction, subst footstep molecules ar changed, and harvest-feast is formed. The enzyme molecule is unchanged after the reaction, and it scum clasp continue to catalyze the same type of reaction everyplace and over. Each enzyme is detail for the reaction it go away catalyze. In this laboratory, Enzyme = catalase Substrate = hydrogen hydrogen peroxide (H2O2) Products = water and convention O H2O2[pic]H2O + O2 If a small amount of catalase is added to hydrogen peroxide, you ordain be able to observe bubbles of group O forming. [pic] Purpose: Enzymes be proteins produced by living cells. They are biochemical catalysts meaning they bring down the activation talent needed for a biochemical reaction to occur. B ecause of enzyme activity, cells lavatory carry out complex chemical activities at relatively low temperatures. The substrate is the substance acted upon in an enzyme-catalyzed reaction, and it can bind reversibly to the active identify of the enzyme.

The active grade is the portion of the enzyme that interacts with the substrate so that any substrate that blocks or changes the shape of the active sit views the activity of the enzyme. The result of this perfunctory union is a reduction in the amount of energy required to activate the reaction of the substrate molecule so that products are formed. The purpose of this lab is to observe a nd understand the do of changes in temperat! ure, pH, enzyme concentration, and substrate concentration on the reaction rate of an enzyme- catalyzed reaction. Another purpose for the lab was to explain how environmental factors carry on the rate of enzyme-catalyzed reactions. Hypothesis: If working under optimum conditions, thusly enzyme catalase noticeably increases the rate of hydrogen peroxide decomposition into oxygen and water.
