• A) One mole of glucose yields 2 moles of glyceraldehyde 3-phosphate.
• B) Two moles of ATP are used during the conversion of glucose to glyceraldehyde 3-phosphate.
• C) Glycolysis produces 2 moles of NADH.
• D) Fermentation of pyruvate to lactic acid yields 2 moles of ATP.
• E) Fermentation of pyruvate to lactic acid yields 2 moles of NAD⁺.
