In ETC, present in the inner mitochondrial membrane, complexes I and IV are respectively
NADH dehydrogenase and FADH2
FADH2 and NADH dehydrogenase
NADH dehydrogenase and cytochrome oxidase complex
NADH dehydrogenase and ATP synthase
Multiprotein complexes in ETC (Electron Transport Chain) -
1. NADH dehydrogenase complex - have prosthelic group FMN, FeS.
2. Succinate dehydrogenase complex - have prosthelic group FAD, FeS.
3. Cyt c - reductase complex - have Cyt b,c
4. Cyt c - oxidase complex - have Cyt a, Cyt c3 , Cua, Cub
5. ATPPase (F0 -F1 particle)
-Hence the correct option is c.
