Which type of respiration do methanogenic bacteria exhibit?

Lactic acid in muscles is formed due to

In anaerobic respiration,

In human skeletal muscle,anaerobic respiration leads to the formation of $.....P.....$,and in yeast cells,anaerobic respiration leads to the formation of $.....Q.....$.

The bacterial decomposition of nitrogenous organic compounds in the absence of abundant oxygen usually results in the formation of substances with an offensive odour,chiefly sulphur compounds. Such anaerobic decomposition is called:

When two molecules of lactic acid are produced from glucose through anaerobic respiration,it results in:
