Question

Quizplus · Accepted Answer

Cytochromes are carrier molecules in the electron transport chain that have a tightly bound metal atom (iron) responsible for accepting and donating electrons. NADH and FAD are electron carriers that donate electrons to the electron transport chain but do not have a metal atom bound to them. Flavoproteins also accept and donate electrons but have a flavin cofactor, not a metal atom. A) NAD⁺ is not a known carrier molecule in the electron transport chain.
