The role of NADH and FADH2 is to donate electrons to the electron transport chain. They both donate electrons by providing an hydrogen molecule to the oxygen molecule to create water during the electron transport chain. NADH is a product of both the glycolysis and Kreb cycles. FADH2 is only produced in Krebs cycle.
