Why are electron carriers (NAD+/NADH and FAD/FADH2) so important in the process of cellular respiration? A)NADH and FADH2 are major components of the ETC, so without them, there would be no ETC in the cell. B)They deliver electrons to the ETC, which in turn sets up chemiosmosis, where most of the ATP is generated. C)They separate the electrons from the protons so that the protons can be moved out of the mitochondrion. D)The electrons that they carry are able to directly phosphorylate ADP in order to generate the bulk of ATP in the cell. E) They transport protons across the mitochondrial membrane. 14.
