There are two stages to the kind of anaerobic cellular respiration you are talking about: One (Glycolysis):
Glucose is broken down via a process called Glycolysis into Pyruvate. Glycolysis does not require oxygen, therefore it can occur in Aerobic (Oxygen rich) or Anaerobic (Oxygen defficient) settings. Two (Ethanol Fermentation):
1. Pyruvate is converted into Acetylaldehyde and CO2.
2. NADH reduces Acetylaldehyde (gives it a proton/ H molecule) which converts it into ethanol (alhohol.) (Both of these phases can be considered Anaerobic, as no Oxygen is used. Glycolysis occurs in any condition (Aerobic/Anaerobic) but Fermentation occurs only in Anaerobic conditions. Ethanol Fermentation occurs only in Anaerobic conditions and in organisms such as yeast and some bacteria. In animal cells, when not enoguh O2 is present, lactic acid is created as a by-product instead of ethanol. (Remember that episode of The Magic School bus when they were inside someone and there was that white goo on their muscles? That was lactic acid.) The purpuse of cellular respiration is to convert sugars into energy that the body can use (ATP, NADH and FADH2.) It is not very efficitnt, and creates much less energy than Aerobic Cellular Respiration would (which performs Glycolysis and then breaks the resulting pyruvate down into CO2 and H2O.)

Why can't we survive with only fermentation?
not enough ATP is produced for our bodies to function
Can candida albicans produce alcohol?
Yes. In 1945, the first case was found in a man named Charlie Swaart. He began experiencing bouts of drunkenness and hangovers, without drinking so much as a single beer! Doctors became puzzled as they detected alcohol on his breath, as well as in his blood. They found that the fungus Candida albicans was the culprit. The cells turned out to be fermenting carbohydrates into alcohol right there in his intestines. Candida albicans is common to find in the digestive tract (and others), but these particular fermenting kind are not.
Two different types of fermentation?
Fermentation is sometimes known as anaerobic respiration - because it usually occurs in the absence of oxygen. However, fermentation is the extraction of energy by oxidation of organic compounds. It does not necessarily have to occur in anaerobic conditions.
Why the process of fermentation is considered biotechnology?
To give a rough definition, biotechnology exploits organisms and their natural processes to allow us to create useful products. Fermentation is to do with the anaerobic respiration of pyruvate into ethanol. This is carried out by microorganisms. As we use the ethanol for alcoholic drinks (either for beer at about 4% alcohol, wine at 12% or if we distill the alcohol, for spirits at 40% abv), we have created a "useful" product; thus it's a biotechnological process.
What organism is used to make beer?
yeast
Is hops the fermenting agent that converts the wort into beer?
No yeast, is the fermenting agent used to make beer.
What micobes are in beer?
Generally yeast is the main agent in fermenting beer.
What is product of glucose and yeast?
fermenting glucose and yeast produces beer and wine.
What is an altbier?
An altbier is a form of German top-fermenting beer which originated in Westphalia.
What is made with fermenting yeast and held in tanks for 2 months at 40 degrees?
beer
Is beer a mineral?
Beer is a mixture of water and alcohol with various flavoring. It is created by fermenting the sugars in grain and adding hops and other flavoring.
What is the difference in production processes of ale beer and lager beer?
The main differences between ale and lager production are in temperature and type of yeast used. Lager is fermented at a lower temperature than ale and uses a bottom fermenting yeast whereas ale uses a top fermenting yeast.
What is an example of anaerobic excercise?
The yeast in beer. It lacks oxygen and so reverts to anaerobic respiration, where the byproduct is alcohol.
Why is anaerobic so important?
we use it to make beer and yogurt
What does a brewmaster do on a typical day?
make beer, drink beer, get drunk, puke it up, go to bed, wake up make beer, drink beer
What is brewers yeast?
Brewer's yeast is an ingredient that is used to ferment sugars to alcohol in the brewing of beer.
What is lager and clarification in brewing beer?
A lager is fermented at relatively cooler temperatures using bottom-fermenting yeast. Compare to an ale, which uses top-fermenting yeast at warmer temperatures. Clarification is the precipitation of the yeast from the finished brew.
