Glycolysis breaks one glucose into two pyruvate molecules while harvesting energy in the form of ATP and NADH. It produces a net gain of 2 ATP per glucose and generates 2 NADH, with two pyruvate molecules as the end products. The two main products often cited are ATP and pyruvate, which is why this option is the best choice. NADH is also produced, but the question highlights the two primary end products. FADH2 is not produced in glycolysis, glucose is the starting material rather than a product, and lactate or ethanol are fermentation products that can arise from pyruvate under anaerobic conditions, not direct products of glycolysis itself.
