Effect of temperature on invertase activity
WebInvertase can be used to demonstrate many features of enzyme activity including the effect of pH and temperature as well as inhibition of the enzyme by the substrate and products. The biochemists Leonor Michaelis and Maud Menten conducted their fundamental studies on enzyme kinetics in 1913 using invertase [1]. Webtemperature is an important factor for enzyme activity because they are directly proportional or related to each other, which means that as temperature Figure 1.0 Preparation of enzyme stock increases, enzyme activity also solution increases. This also means activity II. Preparation of Sucrose Sample decreases at colder temperatures. All
