Second, the enzyme has to transform that substrate into the product. Third, the product must be released. A reaction progress diagram for this process looks something like this: There are some energetic considerations on this diagram that we should think about. When the enzyme is added, the reaction starts, and the enzyme is therefore not included in the master mix. This is not a case where it is crucial to use a master mix; however, the skill is essential for many applications, and it is very useful in enzyme kinetics assays in general. Measure the amount of light that passes through a cuvette. Which wavelenght is optimal to measure NADH. 340 nm. Define the absorbance value displayed on the spectrophotometer.
