Question

which type of relation involves the process of fermentation

Answer 1

did you mean by reaction

then this your answer

Lactic acid. Homolactic fermentation (producing only lactic acid) is the simplest type of fermentation. The pyruvate from glycolysis undergoes a simple redox reaction, forming lactic acid. It is unique because it is one of the only respiration processes to not produce a gas as a byproduct.

Answer 2

Anaerobic respiration involves the process of fermentation....
