Instructor's Note: Students will be required to use Excel to plot absorbance data and fit a line for each substrate concentration in order to calculate initial velocity. In addition, students will graph data to make Michaelis-Menten and Lineweaver-Burke plots.Enzyme and substrate form an ES-complex, which reacts further to enzyme and product.This process requires time, so each enzyme molecule can only handle a certain number of substrate molecules per unit time, called the turnover-number k cat.This number multiplied with the number of enzyme molecules is the limiting reaction velocity, V max, reached only at infinite substrate concentration.Step 1. Conclusion: The enzyme-substrate complex was formed during the enzyme kinetics lab. View the full answer Step 2. Unlock. Step 3. Unlock. Answer. Unlock.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.
