Question

Which is formed during anaerobic respiration

a) Carbohydrates b) Ethyl alcohol c) Acetyl CoA d) pyruvate​

Answer 1

Ethyl alcohol is produced during anaerobic respiration.

• Microorganisms that breakdown sugar in absence of oxygen follow anaerobic respiration. This involves the process of fermentation.
• In alcohol fermentation, the organism uses the pyruvate produced at the end of Glycolysis to produce cellular energy (ATP) along with carbon dioxide and ethanol as by-products.
• Fermentation takes place in the absence of oxygen and produces a lot less energy compared to aerobic respiration.

Answer 2

Answer:

b) Ethyl alcohol is produced during anaerobic respiration.

Explanation:

• The products formed by anaerobic respiration are lactic acid and ethyl alcohol.
• During anaerobic respiration absence of oxygen leads to the breakdown of glucose.
• A complete breakdown of glucose doesn't occur, leading to less production of energy in anaerobic respiration.
• Under anaerobic conditions, at the end of glycolysis, the pyruvate formed produces carbon dioxide and ethanol.
• The fermentation which results in the conversion of sugar into alcohol, gases, and acid is also known as anaerobic respiration.
