Grade 12 Biochemical Pathways

How does fermentation compensate for the lack of oxygen in terms of electron acceptors?
  1. Fermentation creates an alternative pathway for NADH to be recycled back into NAD+.
  2. Fermentation prevents glucose from being completely oxidized so the number of electrons is limited.
  3. Fermentation creates carbon dioxide to serve as the final electron acceptor during the Kreb's cycle.
  4. Fermentation can oxidize many other substances even without the presence of oxygen.
