ed84c Posted February 9, 2004 Share Posted February 9, 2004 How does yeast produce alchohol? Link to comment Share on other sites More sharing options...
Sayonara Posted February 9, 2004 Share Posted February 9, 2004 Basically it's a byproduct of respiration in the yeast. Glucose --> carbon dioxide + ethanol + energy C6H12O6 --> CO2 + CH3CH2OH + Energy Is that what you needed? Link to comment Share on other sites More sharing options...
ed84c Posted February 9, 2004 Author Share Posted February 9, 2004 Why does the yeast not produce 6CO2 and 6H20 like most respirating beings? Link to comment Share on other sites More sharing options...
Sayonara Posted February 9, 2004 Share Posted February 9, 2004 (Without having checked the conversions) I'd guess that the way yeast does it releases more energy per unit energy invested. Link to comment Share on other sites More sharing options...
Ms. DNA Posted February 10, 2004 Share Posted February 10, 2004 ed84c said in post # :Why does the yeast not produce 6CO2 and 6H20 like most respirating beings? Yeast can metabolize glucose by either of two pathways, either with or without oxygen. Without oxygen, it can't process glucose as completely, and that's when the yeast produces alcohol. It does make CO2 when it uses oxygen. Here's a link with more information. Link to comment Share on other sites More sharing options...
Skye Posted February 10, 2004 Share Posted February 10, 2004 By the way, yeast makes cakes and bread rise by producing CO2 using oxygen in your oven. I imagine if you sealed it real good you'd have some sort of wonderous beer cake. Link to comment Share on other sites More sharing options...
Sayonara Posted February 10, 2004 Share Posted February 10, 2004 It'd have to be an electric oven though. Mmmmm beer cake. Link to comment Share on other sites More sharing options...
YT2095 Posted February 10, 2004 Share Posted February 10, 2004 I make beer bread and it`s quite nice! beer cake doesn`t seem that far fetched, no idea what it might tastes like though? it might be worth getting a bottle of Newcastle brown ale and trying it also, I heard many years ago, that you`ll get roughly the same weight in alc as you do in CO2 when something ferments. that applies to both aerobic and anaerobic fermentation (malolactic fermentation however does not, it does improve the taste and gives the drink the Fizz while it`s in the bottle though).

jsatan Posted October 19, 2004 Share Posted October 19, 2004 and they do make bread from Newcastle brown lol. simply great 'a tel' ya. (In a yorkshire accent) Link to comment Share on other sites More sharing options...

Guest meet Posted November 9, 2004 Share Posted November 9, 2004 how would i go about making my own alcohol? it's for an experiment i swear *shift eyes* Link to comment Share on other sites More sharing options...
AngelicTaboo Posted November 9, 2004 Share Posted November 9, 2004 how would i go about making my own alcohol? it's for an experiment i swear *shift eyes* I made ginger beer at college which actually contains alcohol, its quite fun... heres a link if your interested... http://collections.ic.gc.ca/science/english/bio/projects/microbio.html Enjoy Link to comment Share on other sites More sharing options...
