INTRODUCTION Enzyme is a biological catalyst that acts on a molecule called substrate and it also significantly speed up a chemical reaction by lowering the activation energy. In order to learn about the enzyme and its behaviour‚ this lab practical is conducted to examine the kinetic of the enzyme alkaline phosphatase. As illustration‚ when alkaline phosphatase is added to a substrate called p-Nitrophenyl phosphate (colourless in alkaline solution)‚ a series of reaction takes place and eventually
