Quizplus · Accepted Answer

Electrons in the electron transport chain move from complexes with lower electron affinity to those with higher electron affinity. This movement is driven by the increasing affinity for electrons, allowing for the efficient transfer of electrons and the generation of a proton gradient used to produce ATP.
