Study Notes
Cellular Respiration
- Glucose is the starting material for cellular respiration.
- Glycolysis occurs in the cytoplasm, producing 2 ATP and 2 NADH.
- Pyruvate is converted to Acetyl CoA, releasing 2 NADH.
- Acetyl CoA enters the Krebs Cycle.
- The Krebs Cycle occurs in the mitochondrial matrix; producing 2 ATP, 6 NADH, and 2 FADH2.
- Electron transport chain and chemiosmosis takes place on the inner mitochondrial membrane, using the NADH and FADH2 to produce a large amount ATP.
- Oxygen is the final electron acceptor in the electron transport chain.
- Fermentation occurs in the absence of oxygen. This produces a small amount ATP, and sometimes alcohol or lactic acid.
