Question

Which of the following is not formed during anaerobic respiration?

• A. Pyruvate
• B. Ethyl alcohol
• C. CO${}_2$
• D. Acetyl CoA

Answer 1

Answer: (D)

Acetyl CoA

Anaerobic respiration is a type of respiration in which the glucose is partially broken down in absence of oxygen.

Glycolysis is the first pathway that takes place in the cytoplasm and forms pyruvate. During alcoholic fermentation, this pyruvate forms ethanol and carbon dioxide.

Acetyl-CoA enzyme is formed during the aerobic breakdown of glucose.

So, the correct option is 'Acetyl CoA'
