anaerobic metabolism Flashcards
1
Q
Fermentation is
A
the process where extracting energy from fuel molecules relied on organic molecules being an electron acceptor
2
Q
The differiantion of metabolic pathways happens at
A
pyruvate
3
Q
Why do some organisms ferment?
A
- Aerobic organisms use fermentation when oxygen cannot be delivered fast enough
- Organisms may prefer it over oxidative phosphorylation
- Fermentation pathways are for organisms that live without oxygen
4
Q
Latic acid fermentation
A
- occurs in animals and bacteria
- electrons transfer from NADH to Pryuvate
- Lactic acid and NAD+ is produced
5
Q
Ethanol fermentation
A
- occurs in plants and bacteria
- pyruvate releases carbon dioxide forming acetaldehyde
- electrons from NADH are transferred to acetaldehyde
- Ethanol and NAD+ is produced
6
Q
For bacteria cells ETC is in
A
The internal membrane of the mitochondria
