Question

Quizplus · Accepted Answer

Ubiquinone, also known as coenzyme Q10, has the smallest molecular mass of the five types of electron carriers. It has a molecular weight of 863.34 g/mol, compared to flavoproteins (ranging from ~12,000 to 20,000 g/mol), cytochromes (ranging from ~10,000 to 60,000 g/mol), copper atom containing carriers (~50,000 g/mol), and iron-sulfur proteins (~10,000 to 20,000 g/mol).
