Question

In anaerobic respiration, pyruvic acid in the muscles form

• A. Lactic acid
• B. Alcohol
• C. Glucose
• D. None of the above

Answer 1

The correct option is A Lactic acid

• When you run fast or exercise there is a chemical reaction called anaerobic respiration.
• This reaction transfers energy from glucose to your cells without oxygen.
• The extra oxygen you breathe in reacts with the lactic acid in your muscles, breaking it down to make carbon dioxide and water. Hence, In anaerobic respiration, pyruvic acid in the muscles forms lactic acid.

So, the correct answer is 'lactic acid'.
