Ethanol fermentation, also referred to as alcoholic fermentation, is a biological process in which sugars such as glucose, fructose, and sucrose are converted into cellular energy and thereby produce ethanol and carbon dioxide as metabolic waste products. Because yeasts perform this process in the absence of oxygen, ethanol fermentation is classified as anaerobic. Ethanol fermentation occurs in the production of alcoholic beverages and ethanol fuel, and in the rising of bread dough. From Wikipedia under the

Q. The ideal temperature for making ethanol by fermentation is about 37C. Explain why this temperature should not be higher or lower. Asked by Monika J - Thu Feb 5 16:23:19 2009 - - 1 Answers - 0 Comments A. Fermentation is caried out by enzymes which have a temperature optimum - below this optimum (about 37C) the activity will be low and above the optimum the activity will fall as the enzyme loses 3-D structure ,becomes denatured and loses activity. Answered by Peter S - Thu Feb 5 16:37:19 2009 How Can Alcohol (Ethanol) Be Made From Ethene And Fermentation? Q. What are the advantages and the disadvantages? Asked by ummm.... - Mon Jan 15 12:57:49 2007 - - 6 Answers - 0 Comments A. I believe ethene and water will react to for ethanol. This is just a prediction, and even though they shouldn't be able to mix (b/c one is organic and the other isnt), there should still be some solubility. The ethene, a mono unsaturated molecule will become saturated in the presence of water (loosing the double bond), and subsequently pick up the left over OH- to form ethanol, or C2H5OH. I would draw my predicted mechanism but, it would be kinda hard to illustrate using only text! so lets try it like this: C2H4 (ethene) + H2O ~> C2H6 (Ethyl) + OH- OH- + C2H5 ~> C2H5OH Maybe that's how itll happen, maybe not. Just a prediction. :) Answered by Phillip R - Mon Jan 15 13:07:34 2007 What are the actual end products of aerobic respiration and alcoholic fermentation??
Q. Do the end products of aerobic respiration include NADH, FADH2, etc...? or do they only include the ones in the respiration equation (glucose, co2, etc..) and is the only end product of alcoholic fermentation, ethanol? thanks Asked by cutie - Wed Mar 12 23:32:27 2008 - - 1 Answers - 0 Comments A. The actual end products of aerobic respiration are: -Water -ATP -Carbon dioxide If you really want to be specific, NAD+ and FAD+ are also minor end products, even though they cycle back in the process. Glucose is actually a reactant, not a product, of cell respiration. The only end product of alcoholic fermentation is not ethanol. The end products are: -Carbon dioxide -Ethanol -NAD+ Answered by kiddietyte - Wed Mar 12 23:58:31 2008 From Yahoo Answer Search: "Ethanol fermentation" See also:
