E) All of these can be intermediate electron carriers.

Question

Quizplus · Accepted Answer

Coenzyme A is involved in the synthesis and oxidation of fatty acids and in the citric acid cycle but it is not a carrier of electrons in biological redox reactions. Niacin and riboflavin are precursors to NAD+ and FAD, respectively, which are electron carriers. Transition metal ions, such as those of iron or copper, can also act as electron carriers in various biological processes.
