Question

Anaerobic respiration in muscles forms which of the following substances?

Ethanol
Lactic acid
Glucose
Pyruvic acid

Answer 1

Lactic acid is the answer.

Lactic acid fermentation occurs in animals after glycolysis if there is not enough oxygen to perform aerobic respiration. ... One three-carbon molecule (pyruvic acid) is changed into another three-carbon molecule (lactic acid) and no carbon dioxide is produced like during other forms of respiration.

I hope it will help for u ☺.

Answer 2

Hi friend,

The answer will be Lactic acid.

When anaerobic respiration takes place in our body lactic acid +energy is produced .

Sometimes when there is lack of oxygen in our muscle cells,another pathway for the break- down of pyruvate is taken. Here the pyruvate is converted into lactic acid which is also a three carbon molecule. This build-up of lactic acid in our muscles during sudden activity causes cramps.
