The anaerobic process that occurs after glycolysis during lactic acid formation is called:

Alcoholic fermentation takes place in the presence of

In animal muscle cells,lactic acid fermentation occurs when there is poor supply of . . . . . . .

In animal cells,like muscle,during exercise when $O_{2}$ is inadequate for cellular respiration,pyruvic acid is reduced into lactic acid by

Anaerobic respiration in animals produces
