FERMENTATION
-
ALCOHOLIC FERMENTATION
YEAST
- Glycolysis which yields 2 net ATP, 2 pyruvate, and 2 NADH
- The 2 pyruvate is used which will ultimately produce carbon dioxide and 2 ethanol (alcohol), but the derivative of pyruvate shown here, acetaldehyde, can act as an electron acceptor in this process so that the 2 NADH can be oxidized to “ NAD+ so that glycolysis can start all over.
- Since ethanol (alcohol) is a waste product in this process, this is why many yeasts are used to produce alcoholic products. Yeast also can do alcoholic fermentation in making bread, and the carbon dioxide is involved with helping the bread rise.
LACTIC ACID FERMENTATION
MUSCLE CELLS
Lactic acid fermentation could happen if someone is working out very intensely where your blood is unable to deliver a sufficient amount of oxygen to them for their demand.
- we start with glycolysis that yields 2 net ATP, 2 pyruvate and 2 NADH.
- The 2 pyruvate on the reactant side will ultimately yield 2 lactate.
- The pyruvate can act as an electron acceptor allowing NADH to be oxidized to NAD+ so that glycolysis can start over.

Fermentation is a way to be able to handle the little to no oxygen issue: it allows for glycolysis to happen and for glycolysis to keep going. That means making ATP when there is no oxygen. And while you wont make as much ATP in this process as you would aerobic cellular respiration, you can't be too picky when oxygen isn't around.
