Question

In anaerobic respiration, the pyruvic acid in muscle will form

• A. Lactic acid ($C_3{H}_5{O}_3$)
• B. Alcohol ($C_2{H}_{5}OH$)
• C. Acetaldehyde
• D. Acetyl CoA

Answer 1

The correct option is A Lactic acid ($C_3{H}_5{O}_3$)

Skeletal muscles, during the shortage of oxygen undergo anaerobic mode of respiration and thus produces lactic acid from pyruvic acid. The accumulation of lactic acid in the muscles causes muscle cramps. Lactic acid can be converted to glucose in the liver by a process called gluconeogenesis.

So, the correct answer is option A.
