Metabolism without Oxygen Fermentation Principles of

Metabolism without Oxygen Fermentation In aerobic respiration the final electron acceptor for the electron transport chain is an oxygen molecule O 2.If aerobic respiration occurs then approximately 30 molecules of ATP will be produced during the electron transport chain and chemiosmosis using the energy of the high energy electrons carried by NADH or FADH 2 to the electron transport chain.
