Question

How electrons come during nitrogen fixation?

Answer 1

Electrons:

1. A subatomic particle with a negative charge is called an electron. It can either be free (not attached to any atoms) or bonded to an atom's nucleus.
2. Atomic electrons are organized into spherical shells with different radii to represent different energy levels.
3. The energy held within an electron increases with the size of the spherical shell.

Nitrogen fixation:

1. Nitrogen fixation is the process by which atmospheric nitrogen is changed into a form of nitrogen, such as ammonia, either naturally or artificially.
2. In the natural world, the majority of the nitrogen is taken up from the atmosphere by microbes and converted into plant-friendly ammonia, nitrites, and nitrates.

Electrons come during nitrogen fixation:

1. Ferredoxin transfers electrons to the reductase and nitrogenase during the nitrogen fixation process, which turns nitrogen into ammonia.
2. The reductase undergoes conformational modifications as a result of ATP hydrolysis.
3. The eight high-potential electrons in the majority of nitrogen-fixing microbes come from reduced ferredoxin, which is produced during photosynthesis' oxidative activities.
4. Two ATP molecules are hydrolyzed for each electron transported. As a result, at least 16 molecules of ATP are hydrolyzed for every N2 reduced molecule.
