In some electron carriers, small energy transitions may involve cofactors such as:
A) dehydrogenase and oxidases
B) heteroatom and peptide bonds
C) metal ions, conjugated bonds, and heteroaromatic rings
D) none of the above
E) all of the above

Question

Quizplus · Accepted Answer

Metal ions, conjugated bonds, and heteroaromatic rings are common cofactors involved in small energy transitions in electron carriers. Dehydrogenase and oxidases are enzymes that facilitate the transfer of electrons, but are not themselves cofactors. Heteroatom and peptide bonds are not commonly involved in electron carrier systems.
