Action of enzymes as catalysts in biochemical processes * Enzymes acts as catalyst and increase the rate of all the chemical reactions. * Enzymes are also described by two properties like all other catalysts. It composed of two main functions. * The first function is that‚ they increase the rate of chemical reactions by without consumed themselves or undergo any change or alteration in the reaction. . ( Zemitec et‚al 2008). * The second function is‚ they increase reaction rates without

the effects of enzyme concentration on the reaction rate. Part 2: Effect of Substrate Concentration Purpose: The purpose of this part of the lab was to find the effect of substrate concentration on enzyme activity. Part 3: Effect of Temprature Purpose: The purpose of this part of the lab was to determine the effect of temperature on the rate of enzyme activity. Part 4:

Aim: To investigate the factors affecting the stretching of springs and rubber bands Scientific Knowledge: Before doing the experiment I came to the conclusion that this experiment relates to Hooke’s Law which states that extension is proportional to the load‚ meaning that if you stretch something with a steadily increasing force‚ then the length will increase steadily too. By looking at various sources I have also found out that if a mass m on a spring is displaced from the equilibrium position

Introduction How does changing the surroundings of enzymes affect their reaction rate? The purpose of the experiment is to determine how different abiotic conditions affect the rate at which enzymes accelerate/cause reactions In this lab students measured the height of the foam after catalysis between catalase (enzyme) and 7 other (solutions) to determine which solution had the fastest reaction rate.. The control variable of the experiment would be the solution of only hydrogen peroxide‚ water
