  oxygen -     terminal electron acceptor

  The mitochondrial electron transport chain is a series of enzymes and
  coenzymes in the crista membrane, each of which is reduced by the
  preceding coenzyme, and in turn reduces the next, until finally the
  protons and electrons that have entered the chain from either NADH
  or reduced flavin reduce oxygen to water.
The alignment of the ETC components is via their redox potential from the more electronegative to the more electropositive redox potentials.
