Cytochrome electron transport

WebIt mediates the electron transport between complex III and complex IV of the respiratory chain. Cytochrome c has been identified as an important mediator in apoptotic pathways. The release of mitochondrial cytochrome c into the cytoplasm stimulates apoptosis and is commonly used as an indicator of the apoptotic process in the cell. WebThe first step is to transfer electrons via the Fe-S protein to Cytochrome c 1, which reduces cytochrome c. Secondly, the reduced coenzyme Q circulates electrons thru cytochrome c 1, cytochrome b L and intermediate oxidative states of coenzyme Q resulting in the regeneration of one reduced coenzyme Q, one more reduced cytochrome c, and the …
