Your first assignment is to provide information to the firm BigMoney Inc, a chemical producer in Kansas interested in using micr
obes to clean toxic spills (bioremediation). BigMoney Inc. has had a major spill of inorganic Nitrite (N02-) that contaminated the soil around their plant. Scientists at BigMoney have developed mechanisms for removing NH4+ from soil, but have not found one for N02-. They want to know on a strictly theoretical basis (regardless of whether bacteria exist in nature that actually do these specific reactions) if there are any types of bacteria that could metabolize N02- to give rise to NH4+?Nitrite (N02-) to Ammonium (NH4+).a) Is this an oxidation or reduction?b) Is N02- acting as an electron acceptor or donor?
Bacteria that metabolize NO2- to give rise to NH4+ belongs to the family of denitrifying bacteria and nitrate ammonification bacteria such as pseudomonas.
Explanation:
Denitrifying bacteria uses NO2- as electron aceeptor thus converting the nitrite ion (NO2-) to ammonium ion(NH4+).
a) The above reaction is a reduction reaction because NO2- or nitrite ion accept electron to generated its reduced form known as ammonium(NH4+).
b) NO2- acting as electron acceptor in this reaction.
Most likely centripetal force. Newton's first law states that an object in motion will continue to remain in motion unless acted upon by an outside force. In this case, that outside force is the centripetal force.
