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
Which of the correct statement about nitrite reductase characteristics?
