Transcript
Pre-Krebs and Krebs Cycle • Take place in the mitochondria • 2 pyruvate molecules enter the mitochondria from the cytoplasm • 3 Functions: 1. Produces NADH and FADH2 2. Produces ATP 3. Produces oxaloacetate 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 • 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 • 7. Oxaloacetate is regenerated and continues in the Citric Acid Cycle.
