Electron Transport Chain Complexes — NEET Biology
🔥 Predicted for NEET 2027Ubiquinone also receives reducing equivalents via FADH₂ (complex II) that is generated during oxidation of succinate in the citric acid cycle. The reduced ubiquinone (ubiquinol) is then oxidised with the transfer of electrons to cytochrome c via cytochrome bc₁ complex (complex III). Cytochrome c is a small protein attached to the outer surface of the inner membrane and acts as a mobile carrier for transfer of electrons between complex III and IV. Complex IV refers to cytochrome c oxidase complex containing cytochromes a and a₃ and two copper centres.
Adjacent to a frequently-asked paragraph in the same chapter.
Arrange the following components of the electron transport system in the correct order of electron flow during aerobic respiration: 1. Cytochrome bc₁ complex 2. Ubiquinone 3. NADH dehydrogenase 4. Cytochrome c oxidase 5. Cytochrome c
