Last updated Jul 22, 2026
Correct Answer: Option D — I,II,IV and V only
Explanation
Anaerobic respiration occurs in the absence of oxygen and produces different end products depending on the organism:

Alcoholic Fermentation (in yeast and plants): Glucose breaks down into alcohol, carbon dioxide, and energy.

Lactic Acid Fermentation (in animal muscle cells and certain bacteria): Glucose breaks down into lactic acid and energy.

Why Water is excluded:
Water is only formed as a by-product during aerobic respiration, which requires oxygen. It is not produced during anaerobic respiration
