Anaerobic pathways
Why would these pathways be used? Alternate options if:
● No / not enough O2
● No mitochondria (like in prokaryotic bacteria)
Anaerobic pathways
Canvas Notes
What happens:
● ATP generated by glycolysis only!
● Energy carriers recycled and used to power more glycolysis
● Net 2 ATP per glucose - much less ATP than aerobic cellular
respiration!
Two options: lactic acid or alcohol fermentation
Products: Ethyl alcohol + CO2
Products: lactic acid
Ex) Yeast - bread + beer
Ex) muscle soreness &
cheese production
