Anaerobic Energy Pathway

Fermentation Oxygen is not the final e- acceptor after the ETC Bacteria, protistans –Yogurt, yeast Glycolysis –2 NADH –2 ATP –Glucose not completely broken down to CO2 and H2O Fermentation’s final steps –Regenerate NAD+ Not enough energy to sustain a multicelled organism

Lactate Fermentation Pyruvate  Lactic Acid –Accept H+ and e- from NADH Regenerates NAD+ Converts Pyruvate to Lactate (Lactic Acid)

Alcoholic Fermentation Pyruvate  ethanol Yeast –Bread –Wine and Beer
