Question

What is the major source of electrons for reduction of nitrogen?

Answer 1

Answer:

Denitrification is the reduction of oxidized nitrogenous compounds to nitrogen gas (Payne, 1981). This is generally a facultative trait and is carried out by a variety of respiratory bacteria that can utilize oxidized nitrogen compounds (instead of oxygen) as the electron acceptor.

Answer 2

Major source of electrons for reduction of nitrogen is  Ferredoxin.

Explanation:

• Nitrogen fixing processes are aided by various nitrogen-fixing microorganisms.

• The function of these microorganisms is the reduction of nitrogen which is carried out with the help of an electron acceptor called Ferredoxin.

• Ferredoxin is an iron-sulphur proteins which mediate the electron transfer process.

• It releases eight high potential electrons and 2 ATP molecules are hydrolyzed per electron generated making it 16 ATP molecules in total.
