2. fermentation occurs in skeletal muscle cells and red blood cells.
3. alcohol fermentation by yeast produces.
4. in alcohol fermentation, pyruvate is first converted to.
5. in alcohol fermentation, ethanol and are produced.
6. are anaerobic prokaryotes which live in the soil and the digestive tracts of sheep and cows.

methanogens
acetylaldehyde
anaerobic
lactic aid
carbon dioxide
ethanol

Explanation:

1. Anaerobic means without oxygen.
2. Lactic - acid fermentation occurs in skeletal muscle cells and red blood cells.
3. Alcohol fermentation by yeast produces ethanol and carbon dioxide. Acetylaldehyde is an intermediate in the conversion of pyruvate to ethanol in alcohol fermentation.
4. In alcohol fermentation, pyruvate is first converted to acetylaldehyde.
5. In alcohol fermentation, ethanol and carbon dioxide are produced.
6. Methanogens are anaerobic prokaryotes which live in the soil and the digestive tracts of sheep and cows.

Answer:

1. Anaerobic
2. Lactic acid
3. Ethanol and Carbon dioxide
4. Acetylaldehyde
5. Carbon dioxide
6. Methanogens
