Presentation transcript:

Pre-Krebs and Krebs Cycle

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