Although Pyruvate Is the End Product of Glycolysis and No

question 29

Multiple Choice

Although pyruvate is the end product of glycolysis and no more ATP is generated by fermentation of pyruvate to ethanol,yeast produce ethanol under anaerobic conditions because

• A)pyruvate export requires more energy than ethanol export.
• B)electrons (and protons)are then added to ethanol to make lactate.
• C)transfer of electrons from NADH to pyruvate to make ethanol regenerates NAD⁺,which is necessary for new rounds of glycolysis to proceed.
• D)glycolysis substrate-level phosphorylation changes pyruvate to ethanol.
• E)pyruvate to ethanol fermentation decreases deleterious CO₂ levels.
