AIIMS 2014 Botany Respiration MCQ Question

The correct answer is C) partial oxidation of food because fermentation only partially breaks down glucose, resulting in less energy being released compared to aerobic respiration, which fully oxidizes glucose. In aerobic respiration, the complete oxidation of food leads to the production of a greater amount of ATP, the energy currency of the cell, whereas fermentation yields only a small amount of ATP due to its incomplete breakdown of glucose.
