Anaerobic Respiration Flashcards
1
Q
where does it occur?
A
only in cytoplasm
2
Q
anaerobic respiration
A
pyruvate produced in glycolysis reduced by gaining a hydrogen from reduced NAD
3
Q
products in plants and microbes
A
ethanol and carbon dioxide
4
Q
products in animals
A
lactate
5
Q
purpose of anaerobic respiration
A
oxidises NADH so that it can be reused in glycolysis and ensure ATP production is continued
6
Q
efficiency of aerobic respiration
A
- 38 ATP yield, 32% effieciency due to:
- proton leaking across mitochondrial membrane
- ATP being used to actively transport pyruvate and NADH into matrix
- energy lost as heat
7
Q
efficiency of anaerobic respiration
A
- less efficient
- only 2 molecules of ATP produced from one glucose molecule
