FACTORS AFFECTING ENZYME FUNCTION LAB#1 Background randomness Enzymes be vary class of protein that acts as catalysts for the chemical processes deep down our cell which may lapse slowly. To speed up these chemical reactions and for proper function, sepa lay outly enzyme binds with a substratum. The substrate binds to the active situation of the enzyme. This union of substrate to the active site lowers the activation null. This energy reduction allows reactions to occur at faster rate. The enzyme will not function properly, if the formula of the enzyme is denatured or the binding of substrate and enzyme is interrupted. There are several independent, and dep endent variables that affect the enzyme activity. well-nigh of these variables are temperature, PH, season concentration and enzyme and substrate concentration. In this lab, we examined how tether of those factors, temperature, PH and table salt concentration modify the enzyme function.

juicy temperature disrupts the binding of substrate and enzyme. impression temperature decreases the collision between enzymes since the molecules moves slower. PH and salt concentration disrupts the 3- dimensional shape. In this lab, the affects of these factors on the coloured enzyme, catalase was examined. This enzyme is invol ved in the decline of hydrogen peroxide in ! to water and oxygen. Reaction: 2H2O2 ? 2H2O + O2. The rate of enzyme activity decreases as the enzyme is affected by variables such as; temperature and PH. Materials: Please bring in the lab manual. Procedure: Please see the lab manual. remark TABLE 1: Occurrence of enzyme SAMPLE| stride OF ENZYME military action| Liver| 4| Chicken| 1| tater| 2.5| orchard apple tree| 1| TABLE2: Temperature effect on liver enzyme activity...If you essential to trip up a full essay, order it on our website: BestEssayCheap.com
