Could someone explain in a simplified manner how glycolosys(sp?) and Alchohol Fermentation works for a 10th grade bio test?

I have no idea what all those sites on google mean because frankly, I'm not very smart and everything I find is above my level of comprehension.

To anyone that helps me, thanks a ton.

I'm not very smart either, but i don't fool around with alcohol, i simply consume it.

Sorry, not being much of a help here, but i couldn't resist.

Um I dunno. I did bio chemistry, just finish the test, but nothing revolved around alchohol.

However, glycosis is two molecules (forget which substance) bonded together, if that helps.

If I remember my chemistry right it's the following (very simply put):
C6H1206 -> 2(C2H5OH)+ 2(CO2)
--------------------------------
You start out with C6H12O6 (dextrose/grape sugar) and if you leave it long enough (or use a catalyst like yeast) you get 2x C2H5OH (ethanol/common alcohol) and 2x C02 (carbondioxide).
--------------------------------
This however will only work up to a certain concentration of alcohol (around 20%) which is why different methods of destillation are needed to produce spirits.
---------------------
This however is all very simply put so if you want more detail "honk"

In simplest terms, both are ways to create energy.

Alcohol fermentation

1. Alcohol is first converted to acetaldehyde, a toxic and highly reactive substance.

2. Acetaldehyde is then rapidly converted to acetate and then acetyl CoA.

3. Acetyl CoA either enters the citric acid cycle or is made into fatty acids.

Glycolysis

The anaerobic metobolic pathway that breaks a glucose molecule into two molecules of pyruvic acid (or pyruvate) and yields two molecules of ATP (energy) and two molecules of NADH.

Once pyruvate loses CO2 it becomes Acetyl CoA.

Both fermentation and Glycolysis result in Acetyl CoA which goes to the citric acid cycle or Kreb's cycle which is an aerobic process resulting in lots of energy.

So did you get a good grade?

We want feedback, Tom!

I got my test back and i got a 93%. I would of gotten a 98% if I knew what the Krebs Cycle was but, a 93% is decent too thanks for the info
