NADH and FADF2 are the reduced forms of the nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) coenzymes.
<h3>What is nicotinamnde adenine dinucleotide?</h3>
The nicotinamnde adenine dinucleotide (NAD) is a coenzyme used in the transport electron chain of the cellular respiration.
The movement of electrons is coupled to a proton gradient in order to generate ATP, the energy coin of the cell.
