The conversion of ammonium to amino acids requires two enzymes such as GS and GOGAT,

a) High levels of light and carbohydrate—conditions that stimulate plastid GS and Fd-GOGAT

b) Conditions of ample energy inhibit GS and GOGAT

c) The stimulation of GS and GOGAT, they favor nitrogen assimilation into glutamine and glutamate, compounds that are rich in carbon and participate in the synthesis of new plant materials

d) In energy-limited conditions inhibit GS and GOGAT

I. Oxytocin and vasopressin are typical neural hormones , that is, hormones secreted into the circulation by nerve cells.

II. Vasopressin and oxytocin each have a characteristic neurophysin associated with them in the granules in the neurons.

III. The precursor for AVP, prepropressophysin , contains a 19-amino-acid residue leader sequence followed by AVP, neurophysin II, and a glycopeptide. 

IV. Prepro-oxyphysin, the precursor for oxytocin, is a similar but smaller molecule that lacks the glycopeptide.
