Solution
The correct option is C 2
If the oxygen concentration is low, the product of glycolysis is turned into ethanol and carbon dioxide, and the energy production efficiency is low (2 moles of ATP per mole of glucose). If the oxygen concentration grows, pyruvate is converted to acetyl CoA, that can be used in the citric acid cycle, which increases the efficiency to 36 moles of ATP per mole of glucoseSo, the correct answer is '2'
