Does alcohol contain oxygen

Answer 1

Strictly speaking, no, fermentation is the result of anaerobic (without oxygen) respiration of sugar by yeast. But its more complicated than that... Yeast requires oxygen for a number of processes essential for reproduction. Most fermentations involve the initial introduction of oxygen to ensure a strong yeast colony is established. And brewers yeast will ferment without using oxygen even if oxygen is available. Alcohol is toxic to many other organisms (and in high enough concentrations to yeast as well) and by converting sugar to alcohol it can prevent other organisms from getting established.

Answer 2

Oxygen has no role in fermentation. Fermentation is the cellular process of breaking down sugar for energy in the absence of oxygen. When oxygen is used to break sugars down, it is called aerobic cellular respiration, cellular respiration or possibly just respriation if there is little chance that "respiration" will be confused with the "respiration" that refers to breathing.

Answer 3

Alcoholic Fermentation is basically anaerobic fermentation ( in absence of oxygen). However, oxygen is crucial in increasing the population of yeast in initial step called propagation step.

Likewise there is work done and patented in using calculated quantity of pure oxygen in anaerobic fermenter to improve removal of CO2 generated in process. I am not aware of anybody using this method.

Answer 4

Most fungi require oxygen; however, some are able to grow without it. Some are poisoned by oxygen.
No because experiments show the opposite that they don't need O2
Yes.They take in oxygen and give out carbon dioxide like humans.

Answer 5

ithink its because of the enzymes but im not sure

Answer 6

No, beause it is caused by the anaerobic respiration of yeast. Anaerobic means without oxygen.

Answer 7

no, because alcoholic fermentation is a anaerobic respiration.

Answer 8

yes it is

fermentation occurs in anaerobic respiration

Answer 9

Yes.

Answer 10

No.
