Nitrite reductase will convert nitrite to ammonium. There are two types of nitrite reductase characteristics given below;
a) Both nitrite reductase consist of a single 63kD polypeptide
b) In leaf chloroplasts and root plastids contain different forms of the nitrite reductase enzyme
c) In shoot nitrite reductase directly dependent on the light reaction by the ferredoxin, it activates nitrite reductase in choloroplast
d) NADPH in the roots is provided by pentose phosphate pathway, it also activate nitrite reductase in the plastids

NH4+ is toxic to plants, inhibit dinitrogenase and also interfere energy metabolism by dissociating ATP formation from ETC in both mitochondria and chloroplasts. What will plant cells do to avoid this problem?
a) Plant cells avoid ammonium toxicity by rapidly converting the ammonium generated from nitrate assimilation or photorespiration into nitrate
b) Plant cells avoid ammonium toxicity by rapidly converting the ammonium generated from nitrate assimilation or photorespiration into amino acids
c) The pathway for this conversion involves the sequential actions of glutamine synthetase (GS) and glutamate synthase (GOGAT)
d) The pathway for this conversion involves the sequential actions of Aspartate aminotransferase (Asp-AT) and Asparagine synthetase (AS)
Which of the above statements is incorrect?
