Final Acceptor of Electrons in the Electron Transport Chain
The NADH and FADH2 pass electrons on to the electron transport chain which uses the transferred energy to produce ATP. The alternative electron acceptor can be a nitrogen compound nitrate or nitrite a sulfur compound sulfate or sulfite or a carbon.

The electron transport chain is composed of four large multiprotein complexes embedded in the inner mitochondrial membrane and two small diffusible electron carriers.
. The electron transport chain is the portion of aerobic respiration that uses free oxygen as the final electron acceptor of the electrons removed from the intermediate compounds in glucose catabolism. As the terminal step in the electron transport chain oxygen is the terminal electron acceptor and creates water inside the mitochondria. More electron carriers are made and then everything ends up at the electron transport chain.
The electron carriers deposit the electrons at the beginning of the chain and then through a process called chemiosmosis produce many ATP. If that acceptor. Others are strict anaerobes deriving their energy either from glycolysis alone by fermentation or from an electron-transport chain that employs a molecule other than oxygen as the final electron acceptor.
For the electron transport chain to continue working there must be a final electron acceptor.
