Question

Describe in brief nitrate and nitrite reduction in plants..

Answer 1

Answer:

Nitrate reductases are molybdoenzymes that reduce nitrate (NO3-) to nitrite (NO2-).

this reaction is critical for the production of protein in most crop plants, as nitrate is predominant source of nitrogen in fertilised soils.

Answer 2

Answer:

Nitrate is reduced into nitrite in plants this process is called nitrogen assimilation.

Generally, plants take nitrogen from the soil. The soil nitrogen is in the form of nitrate and ammonium.

Nitrate is reduction is taking place in shoots of the plants. Small amount of nitrate reduced by the roots.

NADH or NADPH are used in the reduction process. Anaerobic respiration occurs the inorganic nitrate is reduced into nitrite.

Asimilatory nitrate reductase is involved in this process. This is an enzyme it converts nitrate into nitrite.
