Which is a similarity between alcohol fermentation and aerobic respiration?

The similarity between aerobic respiration and alcohol fermentation is that they both begin with glycolysis.

Explanation:

The process of alcohol fermentation and the aerobic respiration, both begins with the glycolysis step. The alcohol fermentation takes place in the absence of oxygen while the aerobic respiration takes place in the presence of oxygen. The alcohol fermentation (as the name suggests) leads to the production of ethanol, carbon dioxide and very small amount of ATP while aerobic respiration leads to the production of comparatively large amount of ATP and waste products. In alcohol fermentation, Pyruvate is converted into ATP while in aerobic respiration, glucose is converted into ATP.

Hence, the answer is 'Both start with glycolysis'.
