NO3- (nitrate) is taken up into roots, and needs to be converted
to NH4+ and then assimilated into amino acids. Much of this occurs
in root plastids, and requires a lot of energy. From where does the
root plastid get this required energy?
A)Nitrogen fixing rhizobia in root nodules B) Glycolysis C) The
Calvin cycle
D) The light reactions E) Pentose phosphate pathway
