Study Notes
Electron Transport Chain
- The final electron acceptor in the electron transport chain is oxygen.
Oxidative Phosphorylation
- Oxidative phosphorylation occurs in the mitochondria.
Aerobic Glycolysis
- The net ATP yield from one molecule of glucose during aerobic glycolysis is 36-38 ATP.
Electron Carriers
- Coenzyme Q (CoQ) carries electrons to the electron transport chain.
- High-energy electrons are carried by flavin mononucleotide (FMN) and coenzyme Q (CoQ) during cellular respiration.
Krebs Cycle (Citric Acid Cycle)
- The product of the Krebs cycle is ATP, NADH, FADH2, and CoA.
- In eukaryotic cells, the Krebs cycle occurs in the mitochondrial matrix.
Oxidative Phosphorylation Function
- The main function of oxidative phosphorylation in cellular respiration is to generate most of the ATP during aerobic respiration.
