Homework Help: Question about Krebs Cycle

  1. Jun 25, 2010 #1
    1. The problem statement, all variables and given/known data

    What is the total yield of ATP in the Krebs cycle for each glucose molecule that enters glycolysis?

    2. Relevant equations

    3. The attempt at a solution

    Not sure if the correct answer is 2 ATP or 24 ATP due to
    6 NADH (= 18 ATP) oxidative phosphorylation
    2 FADH2 (= 4 ATP) oxidative phosphorylation
    2 ATP substrate phosphorylation
