What is the net yield of ATP from the glycolysis of one glucose molecule?

Answer and explanation

Correct answer: A. Two ATP

  1. Step 1: Two ATP are used in the preparatory phase. Step 2. Four ATP are made in the payoff phase. Answer: a net of two ATP (and two NADH). Why not the others: four is the gross yield and about 30 is the total yield from complete oxidation.
