What are the outputs of glycolysis?

Explanation:
Glycolysis converts one glucose into two pyruvate molecules and, along the way, generates energy-rich molecules. In total, four ATP are formed by substrate-level phosphorylation, while two ATP are consumed earlier in the pathway, so the net gain is two ATP. It also reduces two NAD+ to two NADH. So the outputs you get from glycolysis are two pyruvate, two NADH, and four ATP formed (with a net of two ATP gained). If the question is asking for net yield, you’d report two ATP, but many formulations refer to the total ATP produced, which is four. The other options either include incorrect end products (like oxaloacetate, which isn’t a glycolysis product) or misstate NADH vs NAD+ and the ATP count.
