AAlcohol fermentation
BLactic acid fermentation
CPropionic fermentation
DMixed acid fermentation
Answer & Solution
Correct answer: B. Lactic acid fermentation
1. Lactic acid fermentation is the method used by animals and by certain bacteria such as those in yogurt.
2. It runs routinely in mammalian red blood cells and in skeletal muscle short of oxygen.
3. Muscle worked to the point of fatigue is exactly that oxygen-starved case.
4. Alcohol fermentation produces ethanol and is carried out by yeast rather than by muscle.
