What do you understand by reduction of nitrite?

(a) Reduction of nitrite to ammonia is carried out by an enzyme called nitrite reductase.
(b)This enzyme does not contain molybednum but
requires copper and iron as activators. It requires reducing power, which is NADPH.
© The process of reduction also requires ferrodoxin which occurs in the higher plants mostly in the
leaves and hence this step is carried out in the leaves
