Complex Il (Succinate Dehydrogenase) Path of Electrons Acyl CoA dehydrogenase complex from Succinate, Inner membrane Glycerol-3-phosphate Glycerol-3- dehydrogenase Glycerol-3-phosphate AD →NAD Phosphate, Intermembrane space NAOH+G and Fatty Acids to UQ
Path of Electrons from Succinate, Glycerol-3- Phosphate, and Fatty Acids to UQ Complex II (Succinate Dehydrogenase)
Complex Ill (cytochrome bi) (cytochrome c Reductase) -transfers electrons from reduced CoQ(UQH,to cytochrome c -contains as many as 11 subunits -contains 3 cytochromes:cyt bL,cyt bH cyt ci
Complex III (cytochrome b1 ) (cytochrome c Reductase) -transfers electrons from reduced CoQ (UQH2 ) to cytochrome c -contains as many as 11 subunits -contains 3 cytochromes: cyt bL , cyt bH , cyt c1
Structure of Cytochrome c Member of a group of small proteins called cytochromes all of which contain a heme prosthetic group During electron transport, the Fe in the heme is alternately oxidized and reduced On outer face of inner mito.membrane
