Gallionella bacteria can get energy from the reaction fe2+ → fe3+. this reaction is an example of a. oxidation. b. reduction. c. fermentation. d. photophosphorylation. e. the calvin-benson cycle.

The gallionella bacteria  reaction

that is Fe2+ →  Fe3+ is example of  oxidation reaction (answer A)

Explanation

oxidation reaction reaction occurs when electrons are lost during reaction by a molecule or ion or atom. when oxidation occurs  the oxidation state of the molecule or ion or atom increases. For this reason Fe2+ → Fe3+ is a oxidation reaction since the oxidation state move from oxidation state 2 to 3

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
