Describe the three ways tryptophan synthesis is regulated in a cell.
In try operon by binding of tryptophan on repressor so that tryp repressor can bind on operator
By translation induced trancriptranal attenuation
Describe the three ways tryptophan synthesis is regulated in a cell.
The enzymes required for protein synthesis of the amino acid tryptophan in E. coli are all encoded in a single transcription unit, the trp operon. Transcription of the trp operon is only ignited when the cell has low levels of free tryptophan. Briefly describe how initiation of transcription of the trp operon is regulated in response to the availability of free tryptophan.
14. Describe how the synthesis of nucleotides is regulated. 14. Describe how the synthesis of nucleotides is regulated.
Expression of the trp operon is regulated by the level of free tryptophan in the cell both through repressor action and attenuation. This chart shows the percent expression of the trpoperon in the presence and absence of tryptophan for wild-type (trpR+ or trp+) and repressor mutants (trpR-). Use this information to determine the levels of expression for the following genotypes and conditions. Rank the genotypes and conditions from highest to lowest level of trp operon expression. Please use information below...
One way that tryptophan metabolism in prokaryotes is regulated is “attenuation”. Describe the process of attenuation. Could this process also be found in eukaryotes? Explain.
Describe what is happening in the figure below, and how this corresponds to levels of tryptophan in the cell (2 pts). RNA polymerase DNA Incomplete MKA leader peptide trp-regulated genes
Fatty acid synthesis is regulated in 2 ways. What are they, how do they function, and which one contains the "committed step"?
6. Discuss and explain ways that metabolic pathways are regulated. 7. Outline the three phases of glycolysis and identify the net products. 8. Describe the citric acid cycle and list the net products of the cycle.
5. Summarize the principal ways that metabolic processes are regulated and describe why there are multiple modes of regulation.
Describe how the opposing processes of glycogen breakdown and synthesis are reciprocally regulated by allosteric interactions and the covalent modification of key enzymes.
