During glycolysis, how many NADH molecules are produced per glucose?

Explanation:
During glycolysis, NADH comes from the oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate. One glucose molecule splits into two glyceraldehyde-3-phosphate molecules, so this oxidation happens twice and yields two NADH. The rest of glycolysis focuses on making ATP and does not produce NADH. In cells with oxygen, these NADH molecules can be shuttled into the mitochondria to contribute to ATP production, but the glycolysis step itself provides two NADH per glucose.
