There are 3 steps to solve this one. Expert-verified. 100% (2 ratings)OBJECTIVE: Study of the enzyme kinetics for saccharification of starch using amylase enzyme. THEORY: Reaction of enzyme and substrate follows Michaeli's Menten kinetics and is a two step reaction. In the first phase of reaction Enzyme (E) reacts with Substrate (S) to form ES (Enzyme-Substrate complex). This reaction is relatively fast and reversible in nature. In this enzyme kinetics case, at a specific substrate concentration, a master mix, containing NAD +, N A D plus ethanol, and buffer, can be prepared. The buffer keeps the pH of the reaction mixture stable. When the enzyme is added, the reaction starts, and the enzyme is therefore not included in the master mix.
