1) in plants fixed nitrogen is assimilated into a) serine b) glutathione c) lysine d) threonine e) glutamine 2) the major route for protein degradation discussed in class is a) cytoplasmic proteolytic enzymes b) lysosomes c) ubiquitin proteosomal system (ups) d) both a and b are correct e) all of the above are correct

Glutamine, Ubiquitin Proteosomal system (UPS)

Explanation:

In plants fixed nitrogen is assimilated into Glutamine.

In plants, inorganic nitrogen like nitrate or ammonium is transformed in primary nitrogen assimilation into glutamine & glutamate. This is not, however, the only way for plants to obtain nitrogen from  environment.

The major route for protein degradation  is Ubiquitin Proteosomal system (UPS)

Many intracellular proteins are reduced by ubiquitin-proteasome (UPS) system, a multi-enzyme complex process which involves covalent conjugation of ubiquitin to a substrate protein.
