If anaerobic 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)none of these will occur.

Quizplus · Accepted Answer

Anaerobic pathways following glycolysis can lead to the reduction of pyruvate to either lactate or ethanol, using the two NADH molecules produced during glycolysis. This allows for the regeneration of NAD+ to continue glycolysis in the absence of oxygen, producing a net gain of 2 ATP molecules. CO₂ is not a known product of anaerobic pathways following glycolysis. ATP is not required for the reduction of pyruvate to lactate or ethanol. Oxidative phosphorylation does not occur under anaerobic conditions, as there is no available oxygen to serve as an electron acceptor.
