Using the amino acid tryptophan. Under low glucose conditions, describe the fate of the carbons and of the amino group in either the LIVER OR SKELETAL MUSCLE. Start your answer at the point at which a familiar metabolite or metabolites are produced in the reactions. Your answer should include a description of one way tryptophan could enter the urea cycle and what pathway the carbons will enter in any organ of your choosing.

The trp operon: Bacterial cells can take up the amino acid tryptophan from their surroundings, or, if the external supply is insufficient, they can synthesize tryptophan from small molecules in the cell. When external supplies of tryptophan are plentiful, the cells suppress transcription of the trp operon, which encodes the tryptophan biosynthetic enzymes. When external supplies of tryptophan are not plentiful, the cells express the trp operon. The trp operon repressor protein inhibits transcription of the genes in the trp...
