Which Statement is NOT True of Electron Transport

Question

Which statement is NOT true of electron transport?
A) The mobile electron carrier coenzyme A is located in the inner mitochondrial membrane.
B) Electrons flow from redox centers with a lower reduction potential to redox centers with a higher reduction potential.
C) The electron transport chain oxidizes reduced cofactors.
D) Cytochrome C has a higher reduction potential than FADH2.
E) None of the statements is true.

Accepted Answer

Coenzyme A is not a mobile electron carrier located in the inner mitochondrial membrane; instead, it is involved in metabolic reactions like the citric acid cycle but not directly in electron transport. Mobile electron carriers in the electron transport chain include ubiquinone (coenzyme Q) and cytochrome c.
