Glycolysis Glycolysis SummarySummary
Produces Produces 2 NAD and 4 ATP 2 NAD and 4 ATP moleculesmolecules
• (2 ATP Used & 4 Produced so (2 ATP Used & 4 Produced so overall 2 ATP molecules from overall 2 ATP molecules from glycolysis)glycolysis)
• Pyruvate is oxidized to Pyruvate is oxidized to Acetyl Acetyl CoACoA and and COCO22 is removed is removed
