Cellular electron transport chains

Référence de la vidéo 11937775
Cellular electron transport chains. Animation showing the electron transport chains used by several metabolites to transfer energy to coenzyme Q10 (also called ubiquinone, shown here as UQ). Electron transport chains are used for extracting and transferring energy during metabolic and cellular reactions. The metabolites are shown in and around the inner mitochondrial membrane. The first electron transport chain shown is from nicotinamide adenine dinucleotide (NADH) via flavin mononucleotide (FMN) and an iron-sulphur protein (Fe-S). A similar process for succinate occurs via flavin adenine dinucleotide (FAD) and an iron-sulphur protein. These are known as complex I and complex II respectively (blue, upper left). The other two electron transport chains involve dehydrogenases. At upper centre, glycerol 3-phosphate proceeds via the enzyme glycerol-3-phosphate dehydrogenase (pink) on the outer face of the mitochondrial membrane. At lower right (brown chain), fatty acyl-coenzyme-A (fatty acyl-CoA) transfers electrons via acyl coenzyme-A dehydrogenase and a chain of several FAD intermediates, including the enzyme electron-transferring-flavoprotein dehydrogenase (ETFP). For this animation without labels, see K004/3505.
