G-Protien coupled receptors and how they interact with drugs - CORRECT ANSWERG-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 G...

An increase in ALL of the following would suggest trophic communication or support EXCEPT: 1.# of dendrites & synaptic terminals 2.Size of primary sensory cortex area receiving input from finger 3.Rate of respiration with exercise 4.Density of glial cells in memory areas - ️️3.Rate of respiration with exercise a "Do " communication: a relatively short term 'call to action' (activation) of the respiratory muscles to meet the immediate demands of exercise: increased need of oxygen and...

TSH, LH, FSH are from the same hormone family. They are similar in that they - all contain 2 protein chains and the alpha-chain is each identical Hormone binding/carrier proteins: - help solubilize hormones in blood, protect hormones from being degraded by the liver, reduce concentration of free hormone able to bind receptors Synthesis of norepinephrine from tyrosine - requires enzymatic conversions Phospholipase A2 would be activated - during the synthesis of prostaglandin Insulin affects...

UNC Biol 205 Exam 2 Questions With Verified Answers when cells respond to an extracellular signal, they most often convert the information carried by this molecule from one form to another. What is this process called? - answersignal transduction When does signal transduction begin? - answerwhen the receptor on a target cell recieves and incoming extracellular signal and then produces intracellular signaling molecules that alter cell behavior extracellular signal molecules, released loca...

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...
