Detailed explanation-1: -NADH: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain. FADH2: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain.
Detailed explanation-2: -The main difference between NADH and FADH2 is that every NADH molecule produces 3 ATP molecules during oxidative phosphorylation whereas every FADH2 molecule produces 2 ATP molecules.
Detailed explanation-3: -NADH and FADH2 carry high-energy electrons to the electron transport chain in cellular respiration. NADPH carries high-energy electrons to the electron transport chain in photosynthesis.
Detailed explanation-4: -FADH2 produces less ATP then NADH because NADH has more energetic electrons. FADH2 produces less ATP then NADH because the electrons for FADH2 are dropped off at the second protein of the electron transport chain.
Detailed explanation-5: -The fundamental distinction between NADH and $FADH 2$ is that during oxidative phosphorylation, each NADH molecule makes three ATP molecules, whereas each $FADH 2$ molecule produces two. Furthermore, NADH distributes electrons to Cytochrome Complex I, whereas $FADH 2$ does so to Cytochrome Complex II.
