- The metabolic reactions and enzymes that require NAD/NADH are shown in Figure 1. However, it is not specified whether oxidized or reduced NAD is used in each reaction, nor what form of NAD is produced as a product. Add this specificity to the attached figure. You are also welcome to draw your own figure.Given the following enzyme-catalyzed reaction, identify the class and subclass of the enzyme involved. H H e ООС Class: [Select] Subclass: [Select] COO -H H + FAD H ООС COO + FADH₂Using the symbols X-H2 and Y, draw a coupled oxidation-reduction reaction. Designate the molecule that is reduced and the one that is oxidized and state which one is the reducing agent and which is the oxidizing agent.
