Detailed explanation-1: -Flavin adenine dinucleotide (FAD) is an important redox cofactor involved in many reactions in metabolism. The fully oxidized form, FAD, is converted to the reduced form, FADH2 by receiving two electrons and two protons.

Detailed explanation-2: -An important mechanism in cellular respiration is the transfer of energy to the molecule flavin adenine dinucleotide (FAD) to convert it to FADH2 This is a process of reduction which stores the energy in high electron states in the FADH2.

Detailed explanation-3: -FAD is the oxidized (quinone) form, which is reduced to FADH2 (hydroquinone form) by accepting two electrons and two protons.

Detailed explanation-4: -NAD+ and FAD are oxidizing agents-that is, electron acceptors.

Detailed explanation-5: -A FAD or Flavin Adenine Dinucleotide is a type of co-enzyme that plays a major role in reversible reactions as well as redox reactions.
