Question

Which protein associated with electron transport below is NOT a flavoprotein?
A) NADH dehydrogenase
B) mitochondrial glycerol-3-phosphate dehydrogenase
C) cytochrome oxidase
D) succinate dehydrogenase
E) acyl-CoA dehydrogenase

Cytochrome oxidase is not a flavoprotein; it is a complex of proteins in the electron transport chain that contains heme groups (not flavin) and is involved in the final step of electron transfer to oxygen.
