In which two alternative ways can pyruvate and NADH be metabolized?

Question

Quizplus · Accepted Answer

Pyruvate and NADH can be metabolized through aerobic processes using the Krebs cycle, which is the primary pathway for ATP production in eukaryotic cells. Alternatively, they can be metabolized through fermentation, which occurs in the absence of oxygen and produces much less ATP. However, neither condensation of PGAL nor hydrolysis of PGAL are alternative ways for pyruvate and NADH to be metabolized.
