Question: Identify each highlighted bit as the reducing or oxidizing
agent….or neither, if applicable.


Identify each highlighted bit as the reducing or oxidizing
agent….or neither, if applicable.

Chemolithotrophic Bacteria Chemolithotrophic bacteria obtain energy from redox chemical reactions that involve inorganic compounds. These chemical reactions generally involve some type of membrane-bound electron transport chain to create a proton gradient, which can be used to generate ATP. For each of the metabolic reactions shown, indicate if the highlighted reactant is the reducing reagent (electron donor) or the oxidizing reagent (electron acceptor (RED stands for the reducing reagent, Ox stands for the oxidizing reagent.) For each reaction, the name of a species of bacteria that carries out the chemical reaction is given as an example Gallionella ferrugina2Fe*2 + 1202 + 2H* -» 2Fe+3 H2O Persephonella hydrogen iphila 2HNO3 + 5H2 → N2 + 6H2O Desulfovibrio desulfuricans H2SO4 + 4H2 -> H2S + 4H2O Beggiatoa gigantaH2S 20 H2SO4 Geobacter metallireductans 2Fe3 + H -»2Fef2 + 2H
