Original Khojo Papers practice question — not from a past board paper.
Answer
Fermentation is the anaerobic breakdown of sugar by yeast into ethanol and carbon dioxide: C6H12O6 → 2C2H5OH + 2CO2 + energy. It is used in brewing and in baking, where the carbon dioxide makes the dough rise.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
It releases far less energy than aerobic respiration because the sugar is only partly broken down.
