Question

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

Explanation:

Alcohol fermentation is an anaerobic process and aerobic respiration is an aerobic process. But both start with glycolysis which breaks down glucose into pyruvate. Alcohol fermentation produces alcohol and aerobic respiration does not. Neither requires light - energy. Alcohol fermentation does not require oxygen.

Answer:

Both start with glycolysis.
