- Answer question 17Discuss the advantages and disadvantages of genetic regulation at the different points identified.If there were less substrate than enzyme, then Vmax could never be reached. True or False? Enzymes increase the rate of the forward and reverse reaction proportionally. True or False? The AG of a reaction is related by the Arrhenius equation to the rate constant of a reaction. True or False? Glycogen phosphorylase is phosphorylated and activated by the hormone glucagon. This is an example of transcriptional regulation. True or False? At steady state, the rate of formation of [ES] is equal to the rate of breakdown of [ES). True or False? The Lineweaver-Burk transformation linearizes kinetic data regardless of whether the enzyme follows Michaelis-Menten kinetics. True or False?
- please explain step by step Glucocorticoids- Mechanism of ActionWhich of the following are examples of post- translational modification (PTM)? (select two answers) Genomic DNA is methylated by a DNA methyltransferase, altering the binding of transcription factors. Glycogen phosphorylase becomes active when phosphorylated by glycogen phosphorylase kinase. Glucose is phosphorylated by hexokinase as the first step in glycolysis. Ras is active when bound to GTP, and inactive when bound to GDP. Caspase 3 is activated when cleaved by capsase 9.The glycolytic enzyme pyruvațe kinase is activated by dephosphorylation and inactivated by phosphorylation. O Pre-transcriptional control O Transeriptional control O Translational control O Post-translational control

O mRN would not stop being transcribed from the DNA. O The phosphorylation cascade would continue to release excess phosphates. O mRNA would stop being translated from the DNA. O Receptor proteins would not bind to the signaling hormone.
- Which of the following is NOT a reason cells regulate gene expression at a level other than the transcriptional level? Some proteins are only required in part of the cell and transcriptional control will only regulate the mRNA/protein throughout the cell. The core promoter for many genes is the same, so these genes will always be transcribed in the same cells. Differential gene expression in different cell types requires regulation of gene expression at levels other than transcription. Transcription and translation are realtively slow processes, so cells need to regulate gene expression post-transcriptionally if they require a fast change in expression of a gene. Not all cells are transcriptionally active (meaning they do not transcribe any genes), so these cells need to regulate gene expression post-transcriptionally.When CAMP binds to the Catabolite Activator Protein (CAP), it causes a conformational change on the protein, which results in binding to the CAP- binding site on the DNA and molecule is known as a(n) of the lac operon. This conformational change induced by the binding of another transcription activation; allosteric effect transcription repression; binding effect translation; distortion effect mutation; interactive effect attenuation; compression effect O O O OAt which of these levels isregulation of gene expression most energy-efficient?
