The second messenger in the signaling cascade initiated by glucagon is: correct answer: cAMP Explanation: The second messenger for glucagon is cAMP. Review Module 2 GPCR signaling cascades When insulin is bound to its receptor an autophosphorylation event occurs and the IRS binds these phosphorylated sites through interactions with the: correct answer: SH2 domain Explanation: SH2 domains bind with phosphorylation sites and allow for docking of the IRS with the insulin receptor. Insulin...

Receptors and Signaling, Protein Engineering Exam Questions With Verified Answers. What are the five characteristic features of signal transduction? - answer1. Specificity: a given stimulus triggers a specific response 2. Amplification: a small incoming signal causes a cascade that results in a large response 3. Modularity: different components can be mixed and matched to build a signaling pathway 4. Desensitization: the ability to turn a signaling pathway off 5. Integration: the ability...

G-Protien coupled receptors and how they interact with drugs Correct Answer G-protein coupled receptors (GPCR) interact with drugs through 7 regions of proteins that span and innervate the cell membrane and trap the molecule into the receptor site like an interwoven basket (Insel & Sriram, 2018). Drugs can then enter this space and interact with the GRCP. A specific interaction and binding with a site on one or more of the regions of proteins within the GPCR, and drugs bound with the GRCP can st...

What purpose does glycogen degradation and synthesis serve in animals? correct answers Liver glycogen is short-term energy which provides a way to store and release glucose in response to blood glucose levels. Which of the following is correct concerning the regulation of glycogen metabolism by hormones? -Glycogen phosphorylase is active when phosphorylated, which occurs in response to insulin. -Glucagon activates PKA, which inactivates glycogen synthase -Epi has the same effect as insul...
