ammonium ions are quite toxic to plants and hence cannot be accumulated in them. therefore, plants utilize NH4+ to synthesise amino acids explain the chemical reaction involved in this process

Dear student,
Alpha ketoglutaric acid is the intermediate formed during the Kreb's cycle undergoes reductive amination using ammonium ions and NADH as reducing agent in the presence of enzyme of glutamate synthase to form glutamic acid and further glutamine is formed from glutamate using ammonium ion in the presence of enzyme glutamine synthetase.
