In the electron transport chain,electrons are passed from redox center to redox center ____.
A)spontaneously due to the redox potential gradient.
B)in an ATP dependent fashion.
C)as a result of the addition of free energy.
D)as a result of the proton gradient.
E)with the assistance of a carrier protein.

Question

Quizplus · Accepted Answer

Electrons are passed from one redox center to the next in the electron transport chain spontaneously due to the redox potential gradient. This means that electrons will naturally flow from a higher to a lower potential, and the transfer of electrons from one redox center to the next is energetically favorable.
