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...

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...

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...
