Question

All organisms produce carbon dioxide by burning sugar. then, why do only yeast and few bacteria help in the fermentation?

☆NEED EXPLAINED ANSWER☆

Answer 1

ya its true that all organism produces co2 by braking sugar..

but all organism uses the aerobic respiration which occurs in Presence of o2 ..


but bacteria and yeast do respiration anaerobically which is without use of o2 .

so , that's that's why.....

hope it helps !!!!

Answer 2

Fermentation usually occurs in absence of oxygen. Yeast and bacteria can convert sugars into alcohol releasing carbon dioxide in absence of oxygen. Also, fermentation occurs in some oxygen starved muscle cells (lactic acid fermentation) in animals.
In animals, aerobic respiration occurs which provides energy; however, in absence of oxygen, fermentation (lactic acid fermentation) occurs that produces lactate with no release of additional energy.
