1. Krebs cycle:
- biochemical reactions occurring in all living cells,
- in the inner membrane of mitochondria.
- involves a metabolic pathway (pyruvate --> CO2 + H2O) to generate energy.
- also called citric acid cycle or trycarboxilic acid (TCA) cycle.
2. Acetyl CoA initiates the Krebs cycle (by combining with oxaloacetate (4C) --> citrate).
3. Citrate is decarboxilated and dehydrogenated.
4. Energy stored = NADH, FADH2 and GTP.
5. 2 mol of CO2 are released (as waste product).
6. NAD + FAD = H acceptors.
7. 1 mol of ATP is gained.
