Question

Studying the redox cycling of Fe in the environment has led to the discovery
A) of bacteria that transfer electrons as a form of electricity.
B) of bacteria that destroy toxic metal ions.
C) of archaea that have Fe in their cell walls.
D) that Fe limits primary production in terrestrial ecosystems.

Accepted Answer

Studying the redox cycling of Fe in the environment has led to the discovery of bacteria that transfer electrons as a form of electricity. This is known as extracellular electron transfer (EET) and has applications in areas such as bioremediation and bioenergy production.
