#Unit 6. System Physiology – Plant
Ammonium can be assimilated via an alternative pathway rather than primary pathway which involves the sequential actions of glutamine synthetase(GS) and glutamate synthase(GOGAT), these alternative pathway catalyzes by enzyme known as,

#Unit 6. System Physiology – Plant
Aminotransferases are found in multiple organelles such as cytoplasm, chloroplasts, mitochondria, glyoxysomes, and peroxisomes, these aminotransferases one of its organelles may have a significant role in amino acid biosynthesis such as;

#Unit 6. System Physiology – Plant
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
Which of the following statements about GS and GOGAT is correct?
