Question

Assertion : Fermentation is the incomplete oxidation of glucose into lactic acid or ethanol.\ Reason : Fermentation takes place under anaerobic conditions in prokaryotes only.\

Professor PC Thomas Classes · Answer

(c) : Fermentation is the incomplete oxidation of glucose under anaerobic conditions. In yeast (eukaryote), the pyruvic acid is converted to $\mathrm{CO}_{2}$ and ethanol. Other organisms like some bacteria produce lactic acid from pyruvic acid. In animal cells like muscles, during exercise when oxygen is inadequate for cellular respiration pyruvic acid is reduced to lactic acid by lactate dehydrogenase. Fermentation takes place under anaerobic conditions in many prokaryotes, eukaryotes and in germinating seeds.
