Glycolysis ends in formation of ________ .

Glycolysis is the metabolic pathway that converts glucose into two molecules of pyruvic acid.

It occurs in the cytoplasm of the cell and is the first step of both aerobic and anaerobic respiration.

Lactic acid, acetaldehyde, and ethanol are products formed during fermentation (anaerobic respiration), which takes place after glycolysis.

Therefore, glycolysis ends in the formation of pyruvic acid.

Answer: pyruvic acid
