During glycolysis, one molecule of glucose is broken down into two molecules of pyruvate. The process also produces a net gain of 2 ATP molecules and 2 NADH molecules.
Among the options you listed, the correct one is:
3. 2 ATP, 2 NADH, and 2 pyruvate
(Note: Although the answer mentions 2 ATP and 2 NADH, it seems like a typo in the question since 2 NADH is indeed produced for each glucose molecule.)
