Electron transporters, also known as electron carriers, are tiny organic molecules that play an important role in cellular respiration.
They take electrons from one molecule and transfer them to a different one.
NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide) are two forms of electron carriers that are particularly significant in cellular respiration.
Electron carriers can be reduced or oxidized.
They harvest electrons to form high-energy-yielding products like ATP.
