Detailed explanation-1: -Both NAD+/NADH and FAD/FADH2 are extensively used in energy extraction from sugars during catabolism in chemoheterotrophs, whereas NADP+/NADPH plays an important role in anabolic reactions and photosynthesis.
Detailed explanation-2: -Similarities Between NADH and FADH Both contain an adenine nucleotide. They carry hydrogen and electrons. Also, both of them can take up two electrons. Both carry electrons for the production of ATP during oxidative phosphorylation.
Detailed explanation-3: -Similar to NAD, FAD works in association with a “dehydrogenase” enzyme. The reaction removes two hydrogen atoms; each a proton with one electron. Both hydrogen atoms bond with FAD. This reaction does not release an H+ into solution like the reduction of NAD does.
Detailed explanation-4: -Flavin adenine dinucleotide, or FADH2, is a redox cofactor that is created during the Krebs cycle and utilized during the last part of respiration, the electron transport chain. Nicotinamide adenine dinucleotide, or NADH, is a similar compound used more actively in the electron transport chain as well.
