Substrate-level phosphorylation is used to produce ATP in the absence of O₂.This process depends on _______ to regenerate NAD+.

Question

Quizplus · Accepted Answer

Substrate-level phosphorylation occurs in the absence of oxygen during fermentation, where NADH is generated by glycolysis and converted back into NAD+ through the reduction of pyruvate or other organic molecules. This allows for the continuation of glycolysis and ATP production through substrate-level phosphorylation. The other choices (A, C, D, and E) are not directly involved in the regeneration of NAD+ during substrate-level phosphorylation.
