One of the enzyme that are involve in the ammonium assimilation is Asparagine synthetase (AS), some statements given below about AS such as,
a) This enzyme that catalyzes this reaction, is found in the cytosol of leaves and roots and in nitrogen-fixing nodules
b) High levels of light and carbohydrate inhibit the expression of genes coding for AS and the activity of the enzyme
c) Conditions of ample energy stimulate AS, thus they favor nitrogen assimilation into glutamine and glutamate
d) Energy-limited conditions inhibit GS and GOGAT, stimulate AS, and thus favor nitrogen assimilation into asparagine, a compound that is rich in nitrogen and sufficiently stable for long-distance transport or long term storage
Which of the following statements about AS is correct?

Upon secretion of wnt, When Wnt attaches to the Frizzled receptor on a responding cell, the cell secretes Notum, a hydrolase that associates with glypican and then cleaves off Wnt’s attached lipids in a process of deacylation or delipidation. This process:
