Grade 10 Biochemical Pathways

What statement best describes how fermentation allows cells to produce ATP in anaerobic environments?
  1. Citric acid transforms acetyl CoA into lactic acid or ethanol.
  2. ATP is produced by splitting up pyruvic acid molecules.
  3. Pyruvic acid accepts the energetic electron from NADH, oxidizing it to NAD+ and allowing glycolysis to repeat.
  4. Carbon fixation occurs, which changes RuBP into ATP and splits water molecules.
  5. Oxygen accepts the final electron in the hydrogen ion pump, producing ATP with ATP synthase.
