Question

Which of the following options does not hold good regarding anaerobic respiration of fermentation?

• A. Occurs inside the mitochondria
• B. Partial breakdown of glucose occurs
• C. Net gain of only 2 ATP molecules
• D. None of these

Answer 1

The correct option is A Occurs inside the mitochondria

Fermentation is the incomplete oxidation of glucose under anaerobic conditions by sets of reactions where pyruvic acid is converted to ${CO}_2$ and ethanol (alcoholic fermentation) or lactic acid (lactic acid fermentation). In fermentation, there is a net gain of only 2 ATP molecules for each molecule of glucose degraded o pyruvic acid.
