D)none of these

Question

Quizplus · Accepted Answer

The electron transport chain involves the transfer of electrons from electron donors to electron acceptors via redox reactions, and the flow of electrons is used to create a proton gradient that drives ATP synthesis. It does not involve the transfer of O2 to electrons in the substrate, does not result in a net consumption of ATP (rather, it produces ATP), and the analogy of electrons increasing in energy is incorrect; they actually decrease in energy as they move through the chain.
