If fermentation pathways follow glycolysis, ____.
A) CO₂ will be one of the products as pyruvate is converted to lactate
B) the two NADH molecules produced during glycolysis will (depending on the organism) be used to reduce pyruvate to either lactate or ethanol and CO₂
C) ATP will be required to convert pyruvate to either lactate or ethanol and CO₂
D) oxidative phosphorylation occurs either on the plasma membrane or on derivatives of the plasma membrane
E) ATP will be required to convert lactate to pyruvate and CO₂

Question

If fermentation pathways follow glycolysis, ____.
A) ​CO₂ will be one of the products as pyruvate is converted to lactate
B) ​the two NADH molecules produced during glycolysis will (depending on the organism) be used to reduce pyruvate to either lactate or ethanol and CO₂
C) ​ATP will be required to convert pyruvate to either lactate or ethanol and CO₂
D) ​oxidative phosphorylation occurs either on the plasma membrane or on derivatives of the plasma membrane
E) ​ATP will be required to convert lactate to pyruvate and CO₂

Quizplus · Accepted Answer

The two NADH molecules produced during glycolysis will be used to reduce pyruvate to either lactate or ethanol and CO₂. This is the typical pathway for fermentation, following glycolysis. Option A is incorrect as CO₂ is not produced in the conversion of pyruvate to lactate. Option C is incorrect as ATP is not required for the conversion of pyruvate to lactate or ethanol and CO₂. Option D is incorrect as oxidative phosphorylation does not occur during fermentation. Option E is incorrect as lactate is not converted to pyruvate and CO₂ during fermentation.
