Question

which is a similarity between alcohol fermentation and aerobic respiration?
o both require oxygen.
o both require light energy.
o both start with glycolysis.
o both produce alcohol.

Explanation:

Alcohol fermentation is an anaerobic process and doesn't require oxygen, and neither process requires light energy. Only alcohol fermentation produces alcohol. Glycolysis is the first - stage of both alcohol fermentation and aerobic respiration, breaking down glucose to pyruvate.

Answer:

Both start with glycolysis.
