In order for cells to obtain energy, they remove electrons from an energy source and ultimately donate them to the terminal electron acceptor. What does this tell us about the electron affinity of the energy source and the terminal electron acceptor? The energy source has a lower affinity for electrons, and the terminal electron acceptor has a higher affinity for electrons. This information doesn't tell us anything about the electron affinities of these molecules. The energy source and the terminal electron acceptor have equal but opposite electron affinities. The energy source has a higher affinity for electrons, and the terminal electron acceptor has a lower affinity for electrons.
