Presentation Transcript

  1. Pre-Krebs and Krebs Cycle

  2. Take place in the mitochondria • 2 pyruvate molecules enter the mitochondria from the cytoplasm • 3 Functions: • Produces NADH and FADH2 • Produces ATP • Produces oxaloacetate

  3. Pre-Krebs 1. Pyruvate enters the mitochondria from the cytoplasm 2. CO2 is removed from pyruvate and Acetyl CoA is formed • NAD+ is converted to NADH

  4. Krebs Cycle (Citric Acid) • 3. Acetyl CoA attaches to oxaleacetate creating citrate • 4. Citrate breaks down into intermediates, releasing CO2 • 4. NADH is produced • 5. ATP is formed • 6. FADH2 is produced

  5. 7. Oxaloacetate is regenerated and continues in the Citric Acid Cycle.
