Anaerobic respiration....

Mon May 30, 2005 2:47 pm

I'm confused. I have learned that respiration is anaerobic if the final electron receptor is not oxygen. What about the Krebs cycle? Isn't that an aerobic activity and don't anaerobic bacteria go through a Krebs cycle during respiration?

Thanks,

Krebs cycle and ETS take place in aerobic respiration. Not anaerobic. So, no, anearobic bacteria do not go through a Krebs cycle during respiration.

This is correct. Anaerobes only undergo Glycolysis which leads to other products such as Lactic Acid.

Thank you !

You have really helped me understand how this works.
