does the yeast make it or does the yeast make an enzyme that makes
it.

I seem to see both concepts advanced as true.

what's the truth?

Bilb,

I think it was a chemist named Büchner who found out looong time ago
that enzymes, not whole live cells, are the actual agent of the
fermentation process, although the cells are the source of the enzymes.
In fact, the very word "enzyme" means something like "In the yeast".

Re: regarding alcohol
You are splitting hairs.  Yeast break sugar down as a food source and the
end result is energy for the yeast, CO2 for the atmosphere, and alcohol for
us.  Of course yeast use enzymes as part of the reaction that splits the
sugar.

Its probably easier to go buy yeast then going to the store and asking for
enzymes.Who knows what you'll get..

well, I thought maybe the enzymes were the excrement of the yeast and
they floated around making alcohol.  in retrospect, yeah that doesn't
make a whole lot of sense either, but hey............I hadda ask.

no, the enzymes do the actual work but they are part of the content of the
yeast cells.

Somebody once explained to me that beer is the waste product of yeast.
Basically they eat sugar and pis* out beer....  Hasn't stopped me from
drinking it though.

I bet if you looked on google you probably could find a detailed explanation
of it.  IF you do please post the URL.

Well, not exactly.  Alcohol is the product of yeast consuming the
sugar; the process is fermentation.  If you are making wine, the yeast
there don't "piss" out beer, but they do ferment the sugars present
and the end result is the alcohol in the wine.


Re: regarding alcohol
The yeast make several enzymes that are required for the conversion of
sugar to alcohol.  Yeast, like all living things, are composed of
biological molecules, including enzymes.  So, the enzymes catalyze the
reactions, but the enzymes are part of the yeast.  Its kind of like
asking "do fireflies glow, or is it just a chemical in their tales?"  It
is the philosopher's false dilemma: both are true.
