Anaerobic Respiration
- obligate aerobe: needs oxygen for metabolism, dies in the absence of oxygen
- obligate anaerobe: metabolises in the absence of oxygen, dies in the resence of oxygen
- facultative anaerobe: can metabolise with or without oxygen, can survive in the presence or in the absence of oxygen
in the absence of oxygen:
- only glycolysis can occur
- NADH (and FADH2) can't be reoxidised so can't pick up more hydrogen ions
- therefore the link reacton and the krebs cycle can't occur
- there is a very small yield of ATP
Vertebrae:
- produce lactic acid
- pyruvate becomes the hydroegn acceptor
Plants and Fungi:
- …
