Which of the following statements about "redox potential" is TRUE?

Question

Quizplus · Accepted Answer

Redox potential is a measure of the tendency of a molecule to gain or lose electrons. For molecules that have a strong tendency to pass along their electrons, the standard redox potential is negative, indicating that the molecule has a high affinity for electrons. The transfer of electrons from cytochrome c oxidase to oxygen has a positive redox potential, as oxygen has a high affinity for electrons and therefore accepts electrons readily. Choice A is incorrect because redox potential measures a molecule's capacity to gain or lose electrons, not strip electrons from oxygen. Choice C is incorrect because the transfer of electrons from cytochrome c oxidase to oxygen has a positive redox potential, not a negative one. Choice D is incorrect because a molecule's redox potential is a measure of the molecule's tendency to pass along electrons, not specifically pass along electrons to oxygen.
