When molecular oxygen is unavailable—for example, in plant roots in flooded soils—glycolysis can be the main source of energy for cells, How?

#Unit 6. System Physiology – Plant
  1. In O2 deprived condition, the fermentative pathways are carried out in the chloroplast, must reduce pyruvate to recycle the NAD produced by glycolysis
  2. under lowoxygen conditions (hypoxia), Pyruvate is reduce with loss of its carboxyl group as CO2 , to yield the acetyl group of acetyl-coenzyme A
  3. O2 deprived condition, the fermentative pathways are carried out in the cytosol, must reduce pyruvate to recycle the NADH produced by glycolysis
  4. pyruvate is converted under hypoxic or anaerobic conditions to propanol and CO2 by fermentative pathways  which recyle the NADH produced by glycolysis
