Question

Which is a similarity between alcohol fermentation and aerobic respiration

Answer 1

Answer:

Both processes involves the breakdown of glucose to produce energy.

The first step which is glycolysis is same in both reactions.

Explanation:

• Fermentation is the breakdown of glucose in the absence of oxygen to produce energy.
• While the aerobic respiration is also the breakdown of glucose to produce energy but in the presence of oxygen.
• But in both processes, the glucose first converted to a 3 carbon compound, pyruvic acid. This step is known as glycolysis.
• This step does not involve the oxygen.
• So this is the common step in both reactions.

Answer 2

Alcohol fermentation refers to the anaerobic procedure that comprises the transformation of sugars like glucose into alcohol and carbon dioxide due to the activity of yeasts. On the other hand, aerobic respiration refers to the procedure of generating cellular energy in the presence of oxygen.  

The similarity between the process of aerobic respiration and alcohol fermentation is that both initiate with the process of glycolysis.
