Which represents the production of adenosine triphosphate (ATP) via the aerobic glycolysis system?

• PC + ADP → 1ATP + C

• glucose → pyruvate → 2 ATP + lactate + H+

• glucose → pyruvate + O2

  → acetylCoA → Krebs cycle → electron transport chain →

  38 ATP + H2

  O + CO2

  + heat

• ADP + P = ATP
