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

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

Further ExplanationAerobic respiration.Aerobic respiration is a type of respiration that takes place in living organisms in the presence of oxygen gas. The process involves the breakdown of organic compounds such as glucose to yield energy in the form of ATP and carbon dioxide together with water as byproducts.Anaerobic respiration and alcohol FermentationAnaerobic respiration on the other hand is a type of respiration that occurs in absence of oxygen gas. It involves the breakdown of organic compounds to form small amount of energy in the form of ATP and ethanol or lactic acid as byproducts.Alcohol fermentation is a type of anaerobic respiration where an alcohol is formed as a byproduct. Occurrence.

Aerobic respiration occurs in three stages;

Glycolysis: This is the first stage of aerobic respiration where an organic molecule such as glucose is broken down to form 2 molecules of Acetyl-CoA and net production of 2 ATP molecules. Each glucose molecule yields two molecules of ATP and two molecules of Acetyl-CoA.Kerb's cycle: It is the second phase of aerobic respiration that involves a series of reactions catalyzed by various enzymes. Acetyl-CoA from glycolysis undergoes a series of reaction to produce six molecules of NADH, two molecules of FADH2, together with carbon dioxide and two molecules of ATP.Electron transport chain; This is the final stage of Aerobic respiration, where the six molecules of NADH and two molecules of FADH from Kreb's cycle are used to generate energy in form of ATP. This stage generates 34 molecules of ATP.Stages of Alcohol FermentationGlycolysis; One glucose molecule is broken down to pyruvate and two molecules of ATP are formed.Fermentation; This is the second stage of anaerobic respiration, pyruvate from glycolysis can undergo various steps depending on the living organism. It can be converted to ethanol or lactic acid together with carbon dioxide.When pyruvate from glycolysis is converted to ethanol then it is called alcohol fermentation.
