Mitochondrial Electron Transport System: Definition, Steps, and Reaction for Class 11th, and NEET
Bacterial electron transport and oxidative phosphorylation
Bacteria lack mitochondria, the electron transport system is located in the plasma membrane, and protons are translocated from the cytosol to the plasma membrane’s exterior. In aerobic bacteria, electrons travel from CoQ through cytochrome-based oxidoreductases to O2, which is then reduced to H2O, similar to the mitochondrial system.
