Without oxygen NADH and FADH2 cannot get rid of their electrons. What is the result of this?
Krebs cycle and electron transport stop.
* No NAD for glycolysis
* No NAD for glycolysis
2
New cards
What happens instead to create NAD in animals and plants?
Lactic acid fermentation occurs in animals and alchohal fermentation occurs in plants and yeast.

New cards
What does lactic acid do?
* causes muscle cramps
* when oxygen becomes available lactic acid is converted back to pyruvate.
* pyruvate continues to krebs cycle
* when oxygen becomes available lactic acid is converted back to pyruvate.
* pyruvate continues to krebs cycle

New cards
What happens with sustained lack of oxygen?
2ATP from glycolysis is not enough --> Cell Death
5
New cards
where does anaerobic respiration occur?
Cytoplasm

what do metabolic poisons do?
* Interfere with ETC
* Stops stages of cellular respiration
(ex. cyanide, hydrogen sulfide etc.)
