Why the GS  and GOGAT is activated in light and while the AS is inhibited?

#SCPH06 I Botany
  1. In presence of light and carbohydrate, GS and GOGAT activate so that plant can grow while AS is inhibited so that amino group will not be transported
  2. GS  and GOGAT is activated because they favor nitrogen assimilation into glutamine and glutamate, compounds that are rich in nitrogen and sufficiently stable for long-distance transport or longterm storage
  3. In presence of light and carbohydrate, GS and GOGAT activate so that amino group will be transported while AS is inhibited so that plant can’t grow
  4. AS is inhibited because it favor nitrogen assimilation into asparagine, a compound that is rich in carbon and participate in the synthesis of new plant materials
